Abstract: A comparator including: first and second input transistors connected to control signals at first and second nodes of the comparator; latch circuitry; at least one controllable offset-correction component having an input terminal and connected to control the signal at one of the first and second nodes based on an offset-correction signal provided at its input terminal; for each controllable offset-correction component, an offset correction circuit configured to provide the offset-correction signal provided at its input terminal; and control circuitry. The control circuitry controls the at least one offset-correction circuit to: control an amount by which the offset-correction signal is adjusted; and/or in a bypass operation, connect the input terminal of the at least one controllable offset-correction component to a bypass-operation reference voltage supply; and/or in a maintenance operation, control the charging-operation voltage supply and/or the bypass-operation voltage supply to control leakage of the charge stored on the holding capacitor.
