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 1):
A built-in self-test (BIST) apparatus of an integrated circuit, comprising:\n a reconfigurable capacitor connection matrix; a relaxation oscillator, operable to generate a frequency different from a frequency generated by an oscillator of the integrated circuit, the relaxation oscillator coupled to one or more of a plurality of programmable oscillator capacitors of the oscillator and an oscillator core of the oscillator via the reconfigurable capacitor connection matrix and an output of the relaxation oscillator coupled to the reconfigurable capacitor connection matrix; and a control element coupled to and operable to control the reconfigurable capacitor connection matrix and the relaxation oscillator; where functionality of one or more of the plurality of programmable oscillator capacitors of the oscillator is tested by placement of the oscillator core of the integrated circuit into a high-impedance mode by the control element and measurement of the frequency of the relaxation oscillator as a function of a plurality of programming codes applied to the one or more of the plurality of programmable oscillator capacitors by the reconfigurable capacitor connection matrix.
