Abstract: An oscillator includes a compensated current source that adjusts an output current based on process, supply voltage, and temperature (“PVT”) variations of an integrated circuit device. The oscillator generates an output signal having a frequency based, in part, on the output current of the compensated current source. Accordingly, the output signal has a relatively low sensitivity to PVT variations.
