  • High speed comparator circuit with input-offset compensation function
    Patent number: 4553052
    Abstract: A comparator circuit which can operate at a high-speed and with a high comparison accuracy. The comparator circuit comprises a differential amplifier provided with an input offset voltage compensating circuit which stores the offset voltage and derives an offset-free output signal from the amplifier in response to first and second states of a first control signal and a latch circuit for storing the offset-free output signal in response to a second control signal having a higher frequency than the first control signal.
