hello friends
i am using pmos input two stage error amplifier (0.18um technology). i am using tanner tool can any one tell how to perform psrr analysis , currently i am following these syntax if i am wrong tell me i am not getiing any sensible value of psrr by this analysis. syntax are as follows...
vSource_v_ac_2 N_4 in 0 AC 1.0 90.0>>>>.syntax for ac source connected to supply voltage Vin for dc analysis supply voltage have max value of 1.8 volt
Vin in Gnd dc 1.8>>>supply voltage
Vref ref gnd dc 0.67>>>reference voltage
.ac DEC 5 1 10000MEG
.print V(in) V(out)
.print vdb(out) vp(out)>>output port of error amplifer
.op
.end
