The sampling effect contribution FH(s) is: FH(s)= 1
1+ s
ωn⋅Qp+S2ωn2
(22)
where:
ωn=π⋅fSW
Qp= 1
π⋅[mc⋅(1−D)−0.5]

Error amplifier compensation network
The typical compensation network required to stabilize the system is shown in Figure 36. Transconductance
embedded error amplifier:
Figure 36. Transconductance embedded error amplifier
RC and CC introduce a pole and a zero in the open loop gain. CP does not significantly affect system stability but it
is useful to reduce the noise at the output of the error amplifier.
The transfer function of the error amplifier and its compensation network is:
A0(s)=
AV0⋅(1+s⋅RC⋅Cc)
s2⋅R0⋅(C0+Cp)⋅RC⋅Cc+s⋅(R0⋅Cc+R0⋅(C0+Cp)+Rc⋅Cc)+1
(24)
Where Avo = Gm · Ro
The poles of this transfer function are (if Cc >> C0 + CP):
fPLF= 1
2⋅π⋅R0⋅Cc
