Abstract:
1. An apparatus for generating an output signal having a predetermined duty cycle, the apparatus comprising: a first counter configured to count a first number of cycles of a signal derived from an oscillator signal, the output signal of the first counter configured to transition after the first number of cycles is counted; a second counter configured to count a second number of cycles of the oscillator signal, the output signal of the second counter configured to transition after the second number of cycles is counted, the first and second counters configured to be reset upon a transition in the output signal of the second counter; and a toggle latch configured to generate the output signal having predetermined duty cycle, the output signal of the toggle latch configured to transition from a first state to a second state upon a transition in the output signal of the first counter, the output signal of the toggle latch further configured to transition from the second state to the first state upon a transition in the output signal of the second latch.
