SOI Pixel Based on a Floating Body Partially Depleted MOSFET in a Delta-Sigma Loop

Maher Kayal, Jean-Michel Sallese, Louis Harik

Standard techniques used for measuring the photocurrent of an SOI phototransistor have failed due to two main reasons: the first being the low signal-to-noise ratio and the second being the slow transient. In this paper, the partially depleted silicon on i ...
