Abstract: A transmission channel transmits high-voltage pulses and receives echos of the high-voltage pulses. The transmission channel includes a current generator circuit (104), which generates current-integrator drive currents, a receiver (108), which amplifies transducer-echo signals, and control circuitry (102). The control circuitry generates one or more control signals to control generation of current-integrator drive currents by the current generator circuit during transducer-driving periods and reception of transducer-echo signals by the receiver during echo-reception periods. A current integrator (106) integrates current-integrator drive currents generated by current generator circuit to generate transducer drive signals.

Abstract: The invention relates to a High Voltage switch configuration (10) having an input terminal (IN) which receives an input signal (Vin) to drive a load and an output terminal (OUT) which issues an output signal (Vout) to the load. Advantageously according to the invention, the High Voltage switch configuration ( 10) comprises at least a first and a second diode (D1, D2), being placed in antiseries between said input and output terminals (IN, OUT) and having a pair of corresponding terminals in common, in correspondence of a first internal circuit node (Xc1).

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.
