Patent ID: 8026770

Claim:
A relaxation oscillator comprising: a comparator comprising: a comparator input 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; and a comparator output; a latch comprising: a latch-set input configured to be coupled to said comparator output in response to a third signal; a latch-reset input configured to be coupled to said comparator output in response to a fourth signal; and a latch output configured to output said second signal; and a fourth switching mechanism, wherein said fourth switching mechanism is configured to couple said latch-reset input to ground when said latch-set input is coupled to said comparator output, and wherein said fourth switching mechanism is configured to couple said latch-set input to ground when said latch-reset input is coupled to said comparator output; wherein said relaxation oscillator is configured to achieve an approximately fifty percent duty cycle without requiring use of a second comparator.
