Transmission channel for ultrasound applications
Abstract:
A transmission channel transmits high-voltage pulses in a transmission phase and receives echoes of the high-voltage pulses in a receiving phase. The transmission channel includes a buffer with anti-memory circuitry to couple drain conduction terminals of buffer transistors of a high-side of a buffer of the transmission channel to a low-side reference voltage of a low-side of the buffer and couple drain conduction terminals of buffer transistors of the low-side of the buffer to a high-side reference voltage of the high-side of the buffer during the clamping phase.
