Paper Abstract

In this paper we examine origins of electronic noise in a 127-micron pixel thin film transistor (TFT)/photodiode image sensor array. The imaging array is a 1536 data line by 1920 gate line amorphous Silicon sensor array connected to low noise charge amplifiers and 14-bit electronics. We measure the contributions of A/D converters, charge amplifiers, data-line resistance and capacitance, and pixel switching to the overall electronic noise of 1040 e- per pixel. Noise power spectra are evaluated for each dark offset image.
