    Abstract: There is described a receiver (4) of a signal communication apparatus; the apparatus comprises a transmitter (1) adapted to transmit coded signals, the receiver (4) for receiving the signal and a wireless interface (3) interposed between the transmitter and the receiver and comprising a transmitting antenna (L1) and a receiving antenna (L2). The receiver comprises decoding means (12) of the received signal and first means (9, 10) coupled to the receiving antenna (L2) and capable of triggering said decoding means of the received signal if the value of the received signal is outside a logical hysteresis consisting of a first logic threshold (TH_LO) having a value smaller than the value of the direct current component of the received signal and a second logic threshold (TH_HI) having a value greater than the value of the direct current component (Irde) of the received signal.

    Abstract: Described herein is a self-supply circuit (30), for a voltage converter (1) that converts an input voltage (V in ) into an output voltage (V out ) and has a main switch (10) and a controller (12), designed to control switching of the main switch (10) for controlling the output voltage (V out ); the self-supply circuit (30) is provided with: a charge accumulator (16), which is connected to the controller (12) and supplies a self-supply voltage (V cc ) to the same controller; a generator (24), which supplies a charge current (I charge ) to the charge accumulator (16); and an auxiliary switch (21), which has a first conduction terminal in common with a respective conduction terminal of the main switch (10) and is operable so as to control transfer of the charge current (I charge ) to the charge accumulator (16). In particular, the self-supply circuit (30) is provided with a precharge stage (31), connected to the auxiliary switch (21), which carries out a precharging of an intrinsic capacitance of the auxiliary switch (21) before a turning-off transient of the main switch (10) ends.
