Abstract

This paper presents the error amplifier stage design used in the control loop of an integrated Class D audio amplifier and its performance, especially towards EMC, CMRR and PSRR. The entire amplifier is designed using gpdk_090, a generic 90 nm CMOS process design kit. The input stage is biased with 1.8 V and common mode voltage is around 1.66 V. The error amplifier should have a DC gain of 78 dB and the unity gain frequency should be above 80 Mhz. Conducted emissions requirements are taken from the EN55032 standard. Three well-known topologies are compared which are the Two-stage op-amp, Telescopic and Folded Cascode op-amp. Simulations and layout modeling are carried out in Cadence Virtuoso ADE XL
