Abstract
An oscillator circuit includes a capacitor device, a current source for supplying a current to the capacitor device, a reference voltage, and a control circuit. The reference voltage is a first input to a comparator. An output of the capacitor device and an output of the current source are a second input to the comparator. The control circuit resets the oscillator circuit when the first and second inputs to the comparator are equal.
