Abstract :
A Column-Row-Parallel ASIC architecture is proposed to enable 3D wearable / portable medical ultrasound. It offers linear-scaling interconnection, acquisition and programming time, while supporting rich functionality. High voltage MUX in Tx and specially sized source follower in Rx are used to implement parallelization for improved SNR. Fault-tolerant transceiver handles defective transducer elements to increase assembly yield and allow successful system demonstration.
