摘要：

This paper presents a low pass sigma delta modulator for Analog-to-digital conversion which uses the (SI)-I-2 switched current technique. At circuit level, we propose a new differential pseudo bilinear integrator. Other building blocks such as the 1-bit digital to analogue converter and the quantizer are discussed as well. The whole modulator was implemented in a 0.6 mum threemetal layers digital CMOS process from single 3.3 V power supply. The measured dynamic range is over 8 bits.
