Abstract :
A design of adaptive front-end preamplifier for measurement of optical response of epitaxial photodiode, registering light produced by semiconductor scintillator, is presented. A time constant of continuous-time based pulse shaping filter is adaptively determined to achieve optimal sensitivity for variable parameters of photodetector and readout electronics. Experimental prototype was designed in 0.5µm CMOS process.
