An improved histogram testing method for analog-to-digital converters (ADCs) is proposed. The proposed method reveals not only the static performance but also the dynamic ones, such as the effective number of bits (ENOB) with a sinusoidal input signal. Therefore, single histogram testing is performed rather than using both the histogram and spectral methods to reduce the total test cost. The proposed...
This paper presents a reconstructive oscillator based sinusoidal signal generator which can produce both high and low frequency signals by switching the oscillator into different mode. In addition, analog and digital signals can be produced concurrently in both modes. Also, signal amplitude and oscillation frequency can be precisely controlled compared with pure analog signal generator. Except for...
In this paper, a practical design for built-in current sensors (BICS's) is proposed. This scheme can execute current testing during the normal circuit operation with very small impact on the performance of the circuit under test (CUT). In addition, scalable resolutions and no external voltage/current reference make this design more effective and efficient than previous designs. Moreover this scheme...
