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 19):
The method of  claim 13 , where 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 further comprises:\n selecting a first programmable oscillator capacitor of the plurality of programmable oscillator capacitors; setting a capacitor code of the plurality of capacitor codes for the first programmable oscillator capacitor to a minimum value of a range; measuring the frequency of the relaxation oscillator with the capacitor code of the selected first programmable oscillator capacitor set to the minimal value of the range; selecting a second programmable oscillator capacitor of the plurality of programmable oscillator capacitors; setting a capacitor code of the plurality of capacitor codes for the second programmable oscillator capacitor at the minimum value, incrementally changing the capacitor code from the minimum value to a maximum value of the range and measuring the frequency of the relaxation oscillator at each point along the range; determining a value of the capacitor code applied to the second programmable oscillator capacitor that results in the frequency of the relaxation oscillator being approximately that of the frequency of the relaxation oscillator when the minimum value of the capacitor code is applied to the first programmable oscillator capacitor; and applying the determined value of the capacitor code to the second programmable oscillator capacitor to calibrate the second programmable oscillator capacitor.
