N2 - We propose behavioral time-domain modeling for a Sigma-Delta Modulator (∑ΔM) to sense photocurrent in a CMOS Image Sensor (IS). The model starts from transfer function for first-order single-bit ∑ΔM in discrete-time, and then adds noise sources and nonlinearities by introducing noise floor and harmonic distortion, which determine system performance. The results were compared with the measurements of a CIS based ∑ΔM circuit prototype fabricated with CMOS technology. The model showed good agreement with measurements
