Abstract

The noise-coupling technique successfully used in discrete-time delta-sigma analogue-to-digital converters (ADCs) is extended to the realisation of continuous-time delta-sigma ADCs, resulting in improved quantisation noise shaping. To verify the proposed design methodology, a second-order continuous-time delta-sigma modulator with noise coupling is designed and simulated.
