Error amplifier compensation network
The following figure shows the typical compensation network required to stabilize the system.
Figure 24. Trans-conductance embedded error amplifier
RC and CC introduce a pole and a zero in the open loop gain. The transfer function of the error amplifier and its
compensation network is:
AOs =
AVO∙ 1+s∙RC∙CC
s2∙RO∙CO∙RC∙CC+s∙ RO∙CC+RO∙CO+RC∙CC +1
(13)
Where:
AVO=Gm∙RO
(14)
The poles of this transfer function are (if CC » CO):
