Abstract: An electrical circuit (1) for conversion from differential to single-ended is described, comprising: a differential amplifier stage (2) having a first (IN+) and a second (IN") input; a first (5) and a different second charging circuit (6) of the differential stage that can be operatively coupled, respectively, with an output (OUT*) of the conversion circuit (1) and with an auxiliary output (AUXOUT*). The circuit also comprises a first (7) and a second (8) buffer circuit each functionally arranged between one of said outputs\and between one of said charging circuits. The buffer circuits being configured so as to minimise a difference between the relative impedances seen towards said outputs (OUT*, AUXOUT*).

Abstract: An integrated buffer device (2) for a switched capacity circuit is described, comprising: - a buffer (7) having an output (OUT) for an output voltage dependent upon an input voltage (VIN) that can be supplied by a source (1) to the buffer device; - a capacitative switching component (C I ) that can be switched between a first and second condition in which it is connected, respectively, to the source and to the buffer to transfer the input voltage onto the output; said component being provided with a terminal (N2) having an associated stray capacity (C pi ). The device also comprises a charging and discharging device (SW CPIR , SW G ) configured to pre- charge the stray capacity at a reference voltage (REFM) before taking up the second condition and to pre-discharge the stray capacity before taking up the first condition.
