Abstract
The present disclosure regards adjusting a duty cycle, which includes generating a duty cycle signal having a voltage representing a duty cycle of a clock signal; adjusting a reference voltage generated by an adjustable reference voltage generator to match the duty cycle signal to produce a first matched value; inverting voltage sources of the reference voltage generator; adjusting, while the voltage sources are inverted, the reference voltage to produce a second matched value; and calculating a duty cycle value based on the first and second matched values.
