What is the Transfer Function of an Amplifier?

Up to the previous section, we have explained the concept of transfer function itself in terms of “What is transfer function? From here, we will consider the transfer function of specific circuit blocks. We begin with the “transfer function of an amplifier. Most analog DC/DC converters utilize error amplifiers. Therefore, you will understand that it is essential to derive the transfer function of the amplifier.

In this chapter, we will discuss the following as the basics of transfer functions.

• ・Derivation of the Transfer Functions for Error Amplifiers, Voltage Amplifiers, Current Amplifiers
• ・Amplifier Virtual Short
