Fast PWM-Based Test for High Resolution ?? ADCs
This work describes a novel test strategy that uses digital stimuli for cheap, fast, though accurate, testing of high resolution ?? ADCs. Simulations and measurements showed a discrimination threshold on specification parameters up to ?90dBc. The proposed method helps to reduce the cost of ADC production test, to extend test coverage and to enable built-in self-test and test-based self-calibration.
