- Abstract
- This paper describes the design and implementation of a fully integrated Tx/Rx front-end interface for Doppler Imaging with Piezoelectric Micromachined Ultrasonic Transducer (pMUT). The 4-Level Time Gain Compensation (QL-TGC) readout channel with an integrated biasing bank reduces Rx power with satisfactory noise performance (NF=17) and minimal area. The 65nm CMOS chip occupies 200 x 300 mu m and has a total power consumption of 23 mu W, which is a 4x and 25x improvement over the state-of-art pMUT interface circuits, respectively.
