“…A test circuit, based on a high-gain differential amplifier configuration, has been investigated to determine the frequency-dependence of PSRR. A SPICE PSRR macromodel is described that can be added to most existing (Alexander and Bowers 1990, Jung 1990, Krajewska and Holmes 1979, MicroSim 1993 and new operational amplifier macromodels (Brinson and Faulkner 1994). Design equations are provided for the extraction of the PSRR macromodel parameters, from measured data or manufacturer's data sheets.…”

A new approach to the measurement of operational amplifier power supply rejection, based on the measurement of the power supply injected signal gain of a high-gain differential amplifier configuration, is presented. Measured results for 741 and pin-compatible operational amplifiers are tabulated. A new SPICE macromodel which models operational amplifier power supply rejection characteristics is described. Design equations are provided to extract macromodel parameters from manufacturer's data sheets or measured power supply rejection data. Good agreement has been found between measured operational amplifier power supply rejection characteristics and simulated circuit performance based on the new macromodel.

Abstract.One of the main requirements for generating test patterns for analog and mixed-signal circuits is fast fault simulation. Analog fault simulation is much slower than the digital equivalent. This is due to the fact that digital circuit simulators use less complex algorithms compared with transistor-level simulators. Two of the techniques to speed up analog fault simulation are: fault dropping/collapsing, in which faults that have similar circuit responses compared with the fault-free circuit response and/or with another faulty circuit response are considered equivalent; and behavioral/macro modeling, whereby parts of the circuit are modeled at a more abstract level, therefore reducing the complexity and the simulation time. This paper discusses behavioral fault modeling to speed-up fault simulation for analog circuits.
