Using PSPICE to determine the relative stability of RC active filters

The authors describe a simple procedure for using PSPICE to calculate the relative stability of an active circuit. The active circuit can be implemented using a variety of active devices, including op amps, current conveyors, transimpedance amplifiers, and operational transconductance amplifiers. This procedure can be used with the PSPICE macromodels provided by amplifier manufacturers. This procedure is applied to circuits containing operational transconductance amplifiers and transimpedance amplifiers. Examples are given.<
