Abstract:
A switching circuit for transmission channel for ultrasound applications is electrically coupled between a connection terminal and a low voltage output terminal. The switching circuit includes a receiving switch, a high voltage clamp circuit electrically coupled between the connection terminal and a central node, and a low voltage clamping switch electrically coupled between said central node and a reference voltage. The receiving switch is a low voltage switch and is electrically coupled between the central node and the low voltage output terminal. The clamping switch and the receiving switch are controlled in a complementary way with respect to each other. A transmission channel for ultrasound applications includes the switching circuit.
