Small signal ac analysis
WebThe AC small signal analysis portion of Star-Hspice computes (see Figure 9-1) AC output variables as a function of frequency. Star-Hspice first solves for the DC operating point conditions, which are used to develop linearized, small- signal models for all nonlinear devices in the circuit.
