TRANSCONDUCTANCE AMPLIFIERS
The PFC voltage feedback amplifier is implemented as an
operational transconductance amplifier. It is designed to
have low small signal forward transconductance such that
a large value of load resistor (R1) and a low value
ceramic capacitor (<1μF) can be used for AC coupling
(C1) in the frequency compensation network. The
compensation network shown in Figure 3 will introduce a
zero and a pole at:
