Introduction to BJT Amplifiers and Operational Amplifiers
Free online course on the basic operation of the BJT amplifier, as well as the operation of operational amplifiers.
Description
In this course, you will learn about the basic operation of the BJT amplifier, and also, how the gain is affected by various parameters. Improved biasing schemes, and also, an introduction to the basic form of the BJT small signal model will also be covered in this course. Then, the course will teach you about the common emitter amplifier, and also, combining the DC and the AC solutions.
This course will also teach you about an introduction to the general representation of an amplifier, and also, the advantages of an operational amplifier or op-amp. The op-amp circuit analysis, input and output resistances of the non-inverting amplifier will also be covered in the course. Lastly, you will learn about the operation of the summer, as well as the common-mode rejection ratio or CMRR.
This course is important for learners who want to understand the basic operations of the BJT amplifier. You will also gain an understanding of the operations and advantages of the operational amplifiers or op-amps. Begin this course now to understand the working principles of the BJT amplifier and operational amplifiers.
