[help]How to get the value of input capacitance of opamp?

[pikky]

Dear all,

During simulation using hspice,how can we get the value of the input capacitance of an opamp?

or to be simple, how can we get the value of the capacitance (Cgs or Cgd) of a MOS?

Thanks.

CGSO and CGDO give the values of cgs and cgd caps respectively.

just read the hspice manual ... for details
