Introduction to Classifications and Benefits of Integrated Circuits

Since its first introduction in the year 1958, Integrated Circuits (ICs) have made greater inroads into the technological advancements than any other electronic component. Use of these circuits has helped in the miniaturization of a large number of computers, mobiles, laptops and other electronic devices.

Classification of ICs

These can be classified into analog & digital ICs.

1. Analog ICs

The input and output signals in this type of ICs are continuous. The output signal level is a linear function of input signal level. These output signal levels depend upon the input signal levels.

Applications of analog ICs

It is commonly used as radio frequency amplifier and audio frequency amplifier. Well-known examples of analog ICs are timers, comparators and voltage regulators.

2. Digital ICs

Digital ICs operate with binary data such as 1 and 0. Where 0 indicates 0 volt and 1 indicates +5volt in different digital circuits. Transistors are main components of such circuits. The transistors used in these ICs may be bipolar or field effect depending upon the applications of ICs. The number of transistors incorporated in a single IC chip is increasing, as the technology in the electronic industry is improving day-by-day.

Applications of digital ICs

Some of the popular examples of digital ICs are counters, microprocessors, logic gates, flip flops, logic gates, XOR gate and many more.

Types of sub-classifications of ICs

1. Based on the number of transistors incorporated in a single chip

ICs can be classified into different types, depending upon the number of transistors incorporated in a single chip, like

• Small Scale Integration (SSI)
• Medium Scale Integration (MSI)
• Large Scale Integration (LSI)
• Very Large Scale Integration (VLSI)
• Ultra Large Scale Integration (ULSI)

2. Depending upon the active devices used in ICs

ICs can be classified into as bipolar ICs and unipolar ICs, depending upon the active devices used in the integrated circuits.

3. Sub-classification by modern electronic component distributors

• Mixed-signal ICs can be further sub-categorized by integrated circuits distributor and wholesaler as data acquisition integrated circuits. Some of the popular data acquisition ICs are digital potentiometers, digital to analog converter and analog to digital converter.
• Analog integrated circuits are further sub-categorized by the wholesalers of integrated circuits as radio frequency circuits and linear ICs.
• Digital circuits can be sub-classified by modern Altera integrated circuits distributor into interface ICs such as serializer or deserializer and level shifters. Also, it can be classified into logic ICs and memory chips.
  

Advantages of ICs

• These circuits are thousands time smaller than discrete circuits.
• Owing to miniaturized circuit, the integrated circuit is appreciated for its lightweight.
• It is suitable for small signal operation.
• It is known for its excellent ability of operating at extremely high temperature.
• As many complex circuits can be fabricated into single chip, these circuits are known for their improved functional performance.
• Due to their compact/small design, these circuits are valued for their lower energy/power consumption.
• Elimination of soldered joints and fewer interconnections ensures enhanced functionality.
• Close matching of temperature coefficients and components ensures better efficiency.
• Due to absence of parasitic capacitance effect, the operating speed of these circuits increases compared to discreet circuits.
• It is cost effective to replace them than to repair them.
• It is available at very low cost as mass production of an IC costs as much as an individual transistor.

Conclusion

ICs are one of the more fundamental concepts of electronics. They are complex circuits that contain thousands of electrical components such as capacitors, transistors, diodes and resistors. Today, these electrical components are used in automobiles, computers, mobiles, laptops and many other electronic devices.

Quick View of Different Requirements for Becoming a HR Consultant

Human resource professionals in any organization or consulting firm carry out many important work activities. They play important role in hiring right kind of candidates for available positions in the organization. Also, they suggest the management team how to strategically manage professionals as business resources.

Roles and Responsibilities of Human Resource Professionals

With advancement in technology, the role and responsibilities of human resource professionals have changed over a period of time. Recruitment is one of the important business processes that they handle in any business organization. Through series of examinations, both technical and non-technical, they identify new talent and train them to meet hiring demands efficiently. Key responsibilities of HR professionals include:

1. Identifying hiring needs
2. Developing the position description
3. Recruitment plan development
4. Development of organizational chart
5. Development of other recruitment related documents
6. Conducting recruitments showing good faith efforts to broaden diversity
7. Understanding of collective bargaining agreements’ specific provisions with respect to filling of bargaining unit positions
8. Reviewing recruitments and providing oversight of the recruitment process
9. Routing online recruitment requests to Human Resources for job classification
10. Shortlisting the candidates

• Essential Information

Human Resource (HR) consultants are in great demand in human resource consulting firm. They help to match up the job opening with experienced and qualified candidates. They help a business succeeded in achieving their desired objectives and goals, by assisting in the hiring process.

• Desired Professional Skills

To become successful, applicant should have strong verbal and written communication skills. They should be familiar with human resource software, database program and other customer relationship software.

Knowledge of labor laws, compensation structures and employee benefits is recommended for individuals interested in pursuing a career as HR consultant. They should have knowledge of employee recruitment, hiring and retention procedures.

• Education Qualification

To become a consultant, applicants are required to complete a bachelor’s degree from any reputed institute or university in the US. But only bachelor degree is not enough to make a successful career in this field. So, students also complete different certifications, gain expertise and even complete master’s program in human resource management. Read below to learn about the education qualification needed to become a HR consultant.

1. Bachelor’s Degree

HR consultants are required to have bachelor’s degree, as per the guidelines of U.S. Bureau of Labor Statistics (BLS). However, exact majors and programs of bachelor’s degree can differ. Most of the consultants have a bachelor’s degree in business administration, business management or behavioral science.

In most of the esteemed universities in the United States of America (USA), human resource programs are not typically available in a bachelor’s degree program. Organizational developments, human resources administration, human resources management are some of the minor specializations available for students.

2. Gain Experience

It was found during a survey that employers in the US prefer to hire HR specialists with at least two years of experience in the industry. They work as associate, assistant, specialist or recruiter in entry level HR positions, for the purpose of gaining appropriate experience.

3. Certification

HR professionals may obtain more certifications once employed in any organization or HR consulting firm. These certifications help them gain more skills and expertise.

Professional in human resources and senior professional in human resources are some of the popular certifications offered by “The HR Certification Institute”. Membership with an industry organization, in addition to certifications, help one get better positions.

4. Master’s Degree

Some consultants pursue Master’s degree in labor relations or business administration. Master’s degree is pursued by these consultants while specialization in human resources at bachelors degree program. Many human resources consulting firm in the United States require applicants to have Master’ Degree for advanced HR consultant’s position.

Some of the Common Courses Taken up by Consultants

• Labor history
• Labor economics
• Contract negotiating
• Contact mediating
• Industrial relations
