Abstract:
In this letter, we present an ultrasound (US) imaging system with a low-noise US receiver (RX) and an element-level US transmitter (TX) for a capacitive micromachined ultrasonic transducer (CMUT). The proposed US RX isolates the input parasitic capacitance $(C_{P})$ from the front-end transimpedance stage by using a bandwidth-enhanced current …
