Abstract: A processing circuit for a digital sensor, including: a control stage, which generates a control signal; a multiplexing stage, which may be electrically coupled to a plurality of sensing structures for receiving corresponding detection signals and generates a multiplexed signal, on the basis of one between the detection signals, as a function of the control signal; an analog-to-digital conversion stage, which is connected to the multiplexing stage and generates an encoded signal on the basis of the multiplexed signal; and an equalizer, which multiplies the encoded signal by a coefficient that depends upon the control signal.
