OSCILLATOR SELF-CALIBRATION

Abstract:

An oscillator assembly includes a scribe seal, an oscillator circuit, and a calibration circuit. The oscillator circuit includes an output. The calibration circuit is coupled to the oscillator circuit. The calibration circuit includes a reference frequency terminal, a conductor coupled to the reference frequency terminal, and an oscillator input terminal. The conductor extends to an edge of the oscillator circuit assembly and penetrates the scribe seal. The oscillator input terminal is coupled to the output of the oscillator circuit.
