Abstract:
A built-in self-test (BIST) methodology and apparatus provide for testing and calibration of an integrated circuit oscillator circuit topology that uses a one-pin (a single-pin) external resonator. The method employs dedicated test circuitry, also referred to herein as BIST apparatus, for the pass/fail verification of both the active and passive building blocks of the oscillator. At the same time, the methodology ensures accurate calibration and matching of the capacitors using dedicated digital circuitry and algorithms.

Claim (Index 13):
A built-in self-test (BIST) method for testing an integrated circuit oscillator circuit topology, comprising:\n testing functionality of one or more of a plurality of programmable oscillator capacitors of an oscillator of an integrated circuit by:\n placing an oscillator core of the oscillator into a high-impedance mode, the oscillator core coupled to one or more of the plurality of programmable oscillator capacitors of the oscillator via a reconfigurable capacitor connection matrix; and \n measuring the frequency of a relaxation oscillator as a function of a plurality of programming codes applied to the one or more of the plurality of programmable oscillator capacitors via the reconfigurable capacitor connection matrix, the relaxation oscillator coupled to the plurality of programmable oscillator capacitors by the reconfigurable capacitor connection matrix.
