Abstract

This paper describes the architecture and circuit design of an experimental 8-b differential 15 MS/s CMOS A/D converter, implemented using the switched-current (SI) technique. Particular emphasis has been given to maintaining analog bandwidth and hence the effective number of bits right across the input Nyquist band. Individual cells have also been optimized for inherent accuracy to achieve good performance in a simple uncorrected conversion algorithm. The converter is fabricated in a standard 0.8 μm 5 V digital CMOS process and occupies 2.4 mm²
