Abstract

A transmission channel configured to transmit high-voltage pulses and to receive echoes of the high-voltage pulses includes a high voltage buffer, a voltage clamp and a switch. The voltage clamp may include clamping transistors and switching off transistors coupled together in series with body diodes in anti-series. The transmission channel may include a reset circuit configured to bias the transmission channel between pulses. The switch may include a bootstrap circuit.
