Abstract
An ultra-low noise, high-gain interface pixel amplifier is provided with capability for single-photon readout of known photodetectors at high electrical bandwidths for diverse spectral bandpass from the x-ray to long IR bands. The detector charge modulates a source follower whose output is double sampled to remove correlated noise by a compact stage that also facilitates low-noise gain adjustment for a second gain stage of programmable amplification. Single-photon readout of photodetectors at high electrical bandwidths in small pixel areas is thereby facilitated.
