Webswitch resistances remain approximately constant except for the switches at the output of the OpAmp. For this analysis, all resistances are approximated as constants. A model … WebA conventional sampling circuit (Fig. 4a) consists of a source follower buffer combined with a series sampling switch. The final load capacitance % Åis thus driven by the sum of the output 6 resistance of the source follower and the switch resistance.
