CHOPPER TYPE COMPARATOR

摘要

A chopper type comparator includes an input switch circuit which inputs an input voltage and a reference voltage alternately in response to a control signal; and an output terminal which supplies an output voltage, having a level defined based on the difference between the input voltage and the reference voltage. The comparator further a MOS transistor operating in response to a control signal, and a timing control circuit which provide a delay to the control signal to be supplied to the first MOS transistor and the input switch circuit.
