Abstract

The circuit method of the frequency-response compensation of the input analog section (AS) of the high speed ADCs with the cascade connection of the reference resistors, based on the creation of special conditions for extending of its bandwidth from 200 MHz up to 4÷10 GHz is suggested. The analytical relations for the base block scheme of AS that render possible to calculate the elements of the frequency compensation depending upon the capacitance numerical values of the parasitic capacitors equivalent at the inputs of comparators of ADCs are obtained.
