Abstract
Aspects of the disclosure provide a circuit. The circuit includes a current generator, a capacitor, a comparator, a switch and a clock generator logic. The current generator is configured to generate a current proportional to a comparator threshold voltage by a ratio. The capacitor is configured to be charged by the current to have a capacitor voltage. The comparator is configured to compare the capacitor voltage with the comparator threshold voltage. The switch is configured to discharge the capacitor based on the comparison. The clock generator logic is configured to generate a clock signal based on the comparison, such that a frequency of the clock signal is a function of the ratio and is independent of the current and the comparator threshold voltage.
