摘要：

The present disclosure is generally directed to an ultrasonic transducer interface system for use within portable 2-D ultrasonic imagers and includes an on-chip adaptive beamformer and Charge-Redistribution TX (CR-TX) to provide a drive strength of up to 500 pF/channel at 5 MHz (or 10 nF at 250 kHz) while reducing the TX drive power by at least 30% compared to other ultrasonic transducer TX drivers. The ultrasonic transducer interface system can be implemented in a single chip via, for example, a complementary metal oxide semiconductor (CMOS) process.
