Abstract
A calibration circuit including mode, bias, calibration, offset, resistance and code modules. The mode module selects operation in a first or second mode. The bias module generates, for the preamplifier, a first and second bias currents respectively while in first and second modes. The calibration module, during calibration of first mode, connects inputs of preamplifier together to receive a predetermined voltage. The offset module determines an offset based on output voltages of preamplifier or output voltage of comparator and generates a control signal based on whether the offset is within a predetermined range. The resistance module, based on control signal and during calibration of first mode, adjusts a resistance of a resistor in a first resistance set of preamplifier for the first mode. The code module generates a calibration code based on the resistance. The resistance module calculates a second resistance set for second mode based on the calibration code.
