Abstract
This paper reviews some research aimed at developing suitable circuit techniques to implement high speed ΣΔ modulators on a pure digital process technology. Techniques are presented in both Si and GaAs technologies, and in both instances performance is optimised for speed. Simulations presented for the Si circuits employ MOSFETs from the 0.8 μm Northern Telecom BiCMOS technology
