Delta-sigma modulation has become popular in modern analog-to-digital modulator design due to its relatively high immunity from process variations. We propose efficient characterization techniques to obtain the key performance parameters of the 1-bit first-order delta-sigma modulator which is intended to be used as an on-chip analog signal digitizer for BIST applications. Numerical simulations have been performed to validate the techniques and the results indicate that accurate estimation of the parameters can be obtained at the presence of noise
