Figure 14 shows the gain and phase curves for the
above transfer function with R1 = 2k, C1 = 0.068 μ F, C2
= 470pF, and gm = 0.0015 ? –1. It can be seen that at
15kHz, the error amplifier exhibits approximately 9.6db
of gain and 170° of phase. Figure 13 shows the open
loop transfer function T(s) with these compensation
values. It has a cross over frequency of 15KHz and
phase margin of 60 ? .
