ABSTRACT:
A voltage comparator circuit includes a comparator 42 having a first comparison input, a second comparison input and first and second switched current memories 52, 58 (e.g., switched FETs) connectable, respectively, to the first and second comparator inputs for input voltage offset compensation. In use, during a storage phase, a current value is stored in the switched current memory for each of the first and second comparison inputs and, during a comparison phase, the stored current values are used to compensate for voltage offsets between the comparison inputs.
