Title: Development of PSpice Macromodel for Monolithic Single-Supply Power Amplifiers
Keywords: analog circuits; amplifiers; power integrated circuits; integrated circuit modeling; PSpice; frequency-domain analysis

Abstract: A simple PSpice macromodel was developed, and verified for monolithic power amplifiers operated with a singlesupply voltage. The proposed macromodel is developed using simplification and build-up techniques for macromodeling of operational amplifiers and simulates the basic static and dynamic characteristics, including input impedance, small-signal frequency responses at various voltage gains, output power versus supply voltage, slew-rate-limiting, voltage limiting, output offset voltage versus supply voltage ripples, and output resistance. Furthermore, the macromodel also takes into account the ground reference voltage in the amplifier at a single power supply voltage. The model was implemented as a hierarchical structure suitable for the PSpice circuit simulation platform. The sub-circuit was built using standard PSpice components and analog behavioral (ABM) blocks.
