Abstract
A wideband ΔΣ ADC using a novel double-sampling scheme with a single set of capacitors and a dynamic embedded-adder quantizer is presented. The proposed quantizer eliminates static currents in the adder of a low-distortion architecture. Fabricated in 0.18 µm CMOS process, the prototype chip operates with a 320 MHz sampling frequency and achieves 63 dB SNDR in a 20 MHz signal band while consuming 16 mW power.
