Abstract: A clock generation circuit includes a temperature compensation circuit and an oscillator. The temperature compensation circuit is configured to generate a temperature-compensated frequency selection code that varies depending on an operation temperature based on a difference between the operation temperature and a reference temperature and based on a temperature-independent frequency selection code that is fixed regardless of the operation temperature. The oscillator is configured to generate a clock signal that has an operation frequency that is based on the temperature-compensated frequency selection code, such that the operation frequency is uniform regardless of the operation temperature. Effects of the operation temperature may be reduced by generating the temperature-compensated frequency selection code that reflects the temperature characteristic of the oscillator using the output value of the temperature sensor and by controlling the oscillator using the temperature-compensated frequency selection code.

Abstract: A bandgap reference circuit includes a reference current generation circuit configured to output a bandgap reference current insensitive to a temperature change, by using a first voltage inversely proportional to temperature and a third voltage proportional to temperature. The third voltage is a difference between the first voltage and a second voltage. The bandgap reference circuit further includes a resistivity temperature coefficient cancellation circuit configured to remove a first current proportional to temperature from the bandgap reference current by using the third voltage, and a reference voltage generation circuit configured to output a bandgap reference voltage insensitive to a temperature change by using a second current inversely proportional to temperature and a first resistance proportional to temperature. The second current is generated by removing the first current from the bandgap reference current.

Abstract: A digital phase locked loop circuit includes a phase frequency detector, a bandwidth calibrator, a digital loop filter, and a digital controlled oscillator. The phase frequency detector generates a first detection value and a second detection value of which each is associated with order between a phase of a reference signal and a phase of a fed-back signal. The bandwidth calibrator amplifies a signal level of the second detection value by a gain value to generate an amplified detection value, and adjusts the gain value based on the first detection value. The digital loop filter generates a digital code based on the amplified detection value. The digital controlled oscillator generates an output signal having a frequency which corresponds to the digital code. The fed-back signal is generated based on the output signal and is fed back to the phase frequency detector.
