Abstract
A low power relaxation oscillator circuit includes, in one embodiment, a first comparator for comparing voltages at first and second inputs, respectively, a first capacitor coupled to the first input of the first comparator, and a first circuit configured for charging the first capacitor to a first voltage. The first voltage is related to a propagation delay of the first comparator.
