Abstract:
A sample-and-hold amplifier includes: a switched capacitor network for conducting a sample -and-hold operation on an input signal to generate a first signal; and an operational amplifier coupled with the switched capacitor network and including multiple candidate capacitors; wherein the operational amplifier is arranged to operably generate an output signal based on the first signal, and to operably switch coupling relationship of the multiple candidate capacitors based on the magnitude of the input signal, so that only a portion of the multiple candidate capacitors could be participated in the generation of the output signal at a time.

Claim (Index 13):
The sample-and-hold amplifier ( 700 ) of  claim 12 , wherein the capacitor selection circuit ( 170 ) comprises:\n a plurality of comparators ( 210 ,  220 ) arranged to respectively compare the input signal (Vin) with a plurality of corresponding reference signals (Vref_ 1 , Vref_ 2 ); and a selection logic ( 240 ) coupled with the plurality of comparators ( 210 ,  220 ), and arranged to operably select part of the first through the third candidate capacitors ( 131 - 135 ) to be selected capacitors in the first operation period (T1) according to comparison results of the plurality of comparators ( 210 ,  220 ), and to operably generate multiple control signals for controlling the first through the sixth switches ( 141 - 146 ), so as to couple the selected capacitors to the second gain stage ( 120 ).
