The relaxation oscillator includes a comparator and a latch. The comparator includes a comparator output and a comparator input that is configured to receive a first input signal in response to a first signal and configured to receive a second input signal in response to a second signal. The latch includes a latch-set input that is configured to be coupled to the comparator output in response to a third signal, a latch-reset input that is configured to be coupled to the comparator output in response to a fourth signal and a latch output that is configured to output the second signal. The relaxation oscillator is configured to achieve an approximately fifty percent duty cycle without requiring the use of a second comparator.
