Abstract :
In the fastest analogue to digital (A/D) convertors, the analogue voltage is applied in parallel to an array of 2n ¿ 1 comparators for a simultaneous comparison with a like number of reference voltages. The key element in the parallel A/D convertor is the voltage comparator because it can limit both the speed and the precision. The letter describes a new comparator using GaAs MESFETs designed for parallel A/D convertors operation at gigabit sampling rates.
