  • Patent number: 10060951
    Abstract: In a case in which an input offset voltage of a main amplification circuit deviates from a predetermined range, a retaining operation of retaining an output voltage of a low pass filter in a sample and hold circuit stops, and an output voltage of the low pass filter is directly output to a correction signal supply circuit. As a result, for example, negative feedback control is not temporarily performed due to influence or the like of an excessive input voltage on the main amplification circuit, and in a case in which the input offset voltage of the main amplification circuit deviates from the predetermined range, a response delay due to the retaining operation of the sample and hold circuit does not occur, and the response speed of an offset correction circuit increases.

  • Patent number: 9772354
    Abstract: If an output voltage increases higher than a first limit voltage, a first output transistor is controlled such that the output voltage approaches the first limit voltage, and if the output voltage decreases lower than a second limit voltage, a second output transistor is controlled such that the output voltage approaches the second limit voltage. As a result, it is possible to limit the range of the output voltage and to reduce power consumption, without an increase in an output current at the time of limiter operation, differently from a voltage limiter circuit of the related art.

  • Patent number: 7355490
    Abstract: A receiver includes an up/down counter that controls turning on/off of individual switching units, and a count signal generator that compares a control voltage with a first reference voltage and a second reference voltage lower than the first reference voltage and outputs a count signal to the up/down counter. The count signal generator outputs a down count signal when the control voltage is higher than the first reference voltage, outputs an up count signal when the control voltage is lower than the second reference voltage, and stops the output of the up count signal and the down count signal and outputs a lock signal when the control voltage is between the first reference voltage and the second reference voltage. By the lock signal, a flow of a current in oscillating active elements stops.
