关于全差分运放的仿真，谢谢

I provide my simulation option example for you
as the following
****** v(ip),v(in) are input differential signal
****** v(op),v(on) are output differential signal
****** note if we wish to get vdb(op,on)=20log((v(op)-v(on))/(v(ip)-v(in))  
****** then .option acout must be set to "0"
****** if .option acout set to "1" then  vdb(op,on)=20log(v(op)/v(on)
.option acout=0   *** correct setting
.probe ac   vdb(op,on)   ****to get vdb(op,on)=20log((v(op)-v(on))/(v(ip)-v(in))
*.option acout=1    *** error setting
