摘要

This paper describes a fast charge-integrating sample-and-hold circuit, particularly suited to the fast trigger electronics used with large arrays of photomultipliers in total-energy measurements of high-energy particles interactions. During a gate logic pulse, the circuit charges a capacitor with the current fed into the signal input. The output voltage is equal to the voltage developed across the capacitor, which is held until a fast clear discharges the capacitor. The main characteristics of the fast-charge-integrating sample-and-hold circuit are: i) a conversion factor of 1 V/220 pC; ii) a droop rate of 4 mV/ mu s for a 50 omega load; and iii) a 1 mu s fast-clear time.
