  • Publication number: 20230402998
    Abstract: A comparator module for an oscillator is disclosed. The comparator module has a function provided by two independent comparators that are combined together to share the same bias current source, so that an operation current of the oscillator may be reduced, and the circuit area and power consumption may be effectively reduced. Further, compared to the conventional design that one of the two comparators compares a first voltage with a reference voltage and the other one of the two comparators compares a second voltage with the reference voltage and the time points at which the first voltage and the second voltage are a logic high level are different, three transistors of the disclosed comparator module are designed into two equivalent differential pairs and share a bias current source.

  • Publication number: 20230344384
    Abstract: An oscillator equipped with a temperature compensation circuit is illustrated. Through the temperature compensation circuit, a transistor of a current mirror circuit of the oscillator which outputs a reference current to a voltage matching circuit is controlled by the temperature compensation voltage. Both of the temperature compensation voltage and a reference current decrease as the temperature rises, and a delay time of the oscillation voltage is proportional to the temperature compensation voltage and inversely proportional to the reference current. Therefore, the effects of temperature on the delay time just cancel each other out. The delay time of the oscillating voltage is related to the frequency of the clock signal. Therefore, if the delay time of the oscillating voltage is not affected by temperature, the frequency of the clock signal will not be affected by temperature.
