Abstract

This paper describes the implementation of a continuous-time Delta-Sigma modulator for wireless, instrumentation and measurement applications. The Delta-Sigma modulator employs Gm-C based integrator to form a 4th-order noise-shaping loop. The modulator can achieve 70.7dB of SNDR in 2MHz bandwidth with an oversampling ratio of 40 and single-bit quantization. The modulator is designed in TSMC 0.25μm technology, consuming 3.5mW of power with a reduced power supply of 1.8V.
