  • Patent number: 10644710
    Abstract: The inventive concept includes an oscillating circuit, a phase inverting circuit, and a phase detecting circuit. The oscillating circuit generates a first clock to be used to sample an input signal. The phase inverting circuit outputs a second clock based on the first clock. The phase detecting circuit generates a control signal having a first logic value when a phase difference between a phase of the input signal and a phase of the second clock is less than a reference value for a reference time or more. The phase detecting circuit generates the control signal having a second logic value when the phase difference is equal to or greater than the reference value or when the phase difference is less than the reference value for a time shorter than the reference time.

  • Patent number: 10491208
    Abstract: The inventive concept relates to a semiconductor device including a CMOS circuit and an operation method thereof. A semiconductor device according to an embodiment of the inventive concept includes a semiconductor circuit, a controller, and a voltage generator. The semiconductor circuit operates at a drive voltage to reduce the delay time between input and output as the temperature increases. The controller determines the malfunction of the CMOS circuit based on the difference between the source-drain current of the PMOS transistor and the source-drain current of the NMOS transistor as the temperature changes. The voltage generator generates or adjusts a body-bias voltage applied to the PMOS transistor or the NMOS transistor based on a malfunction determination of the controller. According to the inventive concept, malfunctions and performance deterioration occurring in a CMOS circuit operating at a low voltage may be reduced.
