Efficient and accurate testing of analog-to-digital converters using oscillation-test method
This paper describes a practical test approach for analog-to-digital converters (ADCs) based on the oscillation-test strategy. The oscillation-test is applied to convert the ADC under test to an oscillator. The oscillation frequencies are able to monitor the ADC conversion rate, differential nonlinearity (DNL) and integral nonlinearity (INL) at each quantization band edge (QBE). Using this method, no analog stimulus should be supplied and therefore the need for a costly precision signal generator is eliminated. Besides, as the oscillation frequency is evaluated using pure digital circuitry, test accuracy is increased. This test approach is not limited to a special kind of ADC. Simulations and practical implementation prove the efficiency of the proposed test approach for ADCs.
