Fully digitized 2D ultrasound transducer arrays require one ADC per channel with a beamforming architecture consuming low power. We give design considerations for per-channel digitization and beamforming, and present the design and measurements of a

Dynamic receive beamforming on a Delta-Sigma modulator's low-resolution output bit-stream suffers from a severely increased noise floor, rendering the promising method infeasible. This paper addresses the mechanism behind the increased noise floor. B

A 5th order continuous time delta sigma modulator is designed in 0.18μm CMOS. At a sampling rate of 500MHz it achieves 76dB SNDR over a 10MHz bandwidth consuming 58mW. 5th order noiseshaping is realized with 4 opamp based RC integrators and a VCO re
