Abstract
In certain aspects, a clock generator includes a ring oscillator including an input and an output. The clock generator also includes a count circuit including an input and an output, wherein the input of the count circuit is coupled to the output of the ring oscillator. The clock generator also includes a comparator including a first input, a second input, and an output, wherein the first input of the comparator is configured to receive a first count value, and the second input of the comparator is coupled to the output of the count circuit. The clock generator further includes a shift register including a shift control input and an output, wherein the shift control input is coupled to the output of the comparator, and the output of the shift register is coupled to the input of the ring oscillator.
