Brinson, Mike and Faulkner, D. J. (1994) SPICE macromodel for operational amplifier power supply current sensing. Electronics Letters, 30 (23). pp. 1911-1912. ISSN 0013-5194

Abstract

A SPICE macromodel is described which may be added to any operational amplifier macromodel to simulate variations in power supply current with load current. This allows modelling of circuits using supply-current sensing and examination of the effects of power supply transients. Performance is illustrated by modelling a precision full-wave rectifier using the mu A741 operational amplifier.
