I overleaped the netlist here.........following is the controlled description.
------------------------------------
V_VSA vsa 0 DC=0 V_VDA vda 0 DC=3
V_vip vip 0 DC=1 I_IIN 0 iin DC=2.5uA v_vim vim 0 1 AC=1 $ ac source R_AC_COUPLE vim vimz 1e9 ac=0 .
R_self-bias vout vimz 1m ac=1e30
c_load vout vsa cval $ varying load capacitance .TEMP 25 .options nomod numdgt=6 acout=0 runlvl=0 accurate post probe .prot .lib 'mm06.l' tt .unprot
.op .param cval=0 .AC DEC 10 1m 10MEG .print AC vdb(vout) vp(vout) v(*)
.alter .param cval=1p
.alter .param cval=10p
.alter .param cval=100p
.end
----------------------------------------------
I'm fresh ,pls see my questions below:
1,Through viewing the phase waveform,it has two turnings,whether means it has 2-pole response?and how did you calculate it?
2,How does change in load capacitance affect pole location(s)?
Need your helps, thanks in advance!
