Abstract

A high resolution 1bit Sigma-Delta modulator for low power/low voltage applications is presented. The modulator operates at a supply of 1-1.5V, the current drain is 0.1mA. The maximum resolution is 87dB equivalent to 14 bits of resolution. This is achieved with a signal-band of 5kHz, over-sampling ratio (OSR) of 128 and a sampling frequency of 1.28MHz. The very low power consumption is achieved by using a new type of efficient class AB amplifiers in a fully differential configuration. The modulator is implemented in a 0.7 micron n-well CMOS technology. Optimisation details concerning modulator coefficients and bias requirement of amplifiers is described.
