Abstract
An oscillator circuit includes a comparator having first and second inputs, the first input configured to be coupled to a reference voltage. The oscillator circuit also includes a capacitor and a first current source. The capacitor is coupled between the second input and ground. The first current source is coupled between a supply voltage terminal and the capacitor. The first current source is configured to generate a current to the capacitor that is proportional to absolute temperature.
