The present disclosure includes calibration circuitry for adjusting the bandwidth of at least one sub-converter of an interleaved analog to digital converter (ADC), the at least one sub-converter having an input switch coupled to an input line of the ADC, the calibration circuitry having a control circuit adapted to adjust a bulk voltage of a transistor forming the input switch.

Interleaved ADC calibration

Device for processing an analogue signal, comprising an analogue-digital converter with a pipelined architecture having an offset, and compensation means configured to compensate for the said offset, the said compensation means comprising digital correction means configured to correct the integer portion of the offset based on the digital signal delivered by the analogue-digital converter, and analogue correction means included in the last stage of the analogue-digital converter and configured to correct the decimal portion of the offset.

Device and method for processing an analogue signal

A generator capable of supplying one or more output signals with a modulated cyclic ratio includes one or more formatting circuits each processing one input signal and one or more class D amplifiers powered with a power supply voltage and being driven by a corresponding one of the formatting circuits. Each formatting circuit has a counter-reaction loop and uses a reference voltage for which the average value is equal to half the power supply voltage. The corresponding output signal is thus corrected for any variations in the power supply voltage.
