Because of their relative robustness to process variation, Σ-Δ modulation techniques are particularly suitable for VLSI implementations. In this paper, we propose to employ the 1-bit Σ-Δ modulation ADC (analog-to-digital converter) as the on-chip analog response extractor for analog/mixed-signal BIST (built-in self-test) applications. To validate the idea, a prototype chip with the proposed BIST circuitry has been designed and fabricated. Performance of the BIST circuitry is validated (up to 87 dB dynamic range), and measurement results of the circuit under test (CUT), a 2nd-order low-pass filter, are presented.
