Abstract (en)

[origin: WO2023020680A1] Circuitry (400) for controlling the amplification of an input signal (408), the circuitry (400) comprising: an amplifier (401) for receiving an input signal (408) and being configured to amplify the input signal (408) to generate an amplified signal (409); a cascading series of N comparison blocks (403), C1, C2, … Cn-1, Cn, … CN, each comparison block (403), Cn, being for receiving a reset input signal (412) from a previous comparison block (403), Cn-1, and being configured to receive the amplified signal (409); wherein each comparison block (403) is further configured to control its state in dependence on the reset input signal (412) and the amplified signal (409). In this way, the control of each comparison block (403), and consequently the control of the amplifier (401), may be dependent on the reset signal (413) from the previous comparison block (403) in the cascading series of comparison blocks (403).
