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 6):
The sample-and-hold amplifier ( 700 ) of  claim 2 , wherein the switched capacitor network ( 702 ) comprises:\n a sampling capacitor ( 710 ); a first sampling switch ( 720 ) coupled with a first terminal of the sampling capacitor ( 710 ), and arranged to selectively couple the sampling capacitor ( 710 ) to the input signal (Vin) or the output signal (Vout); a second sampling switch ( 730 ) coupled with a second terminal of the sampling capacitor ( 710 ), and arranged to selectively couple the sampling capacitor ( 710 ) to a second predetermined voltage (Vcmi) or an input terminal of the first gain stage ( 110 ); and a timing control circuit ( 740 ) coupled with the first sampling switch ( 720 ) and the second sampling switch ( 730 ), and arranged to operably control switching timings of the first sampling switch ( 720 ) and the second sampling switch ( 730 ); wherein the second sampling switch ( 730 ) couples the sampling capacitor ( 710 ) to the second predetermined voltage (Vcmi) when the first sampling switch ( 720 ) couples the sampling capacitor ( 710 ) to the input signal (Vin); and the second sampling switch ( 730 ) couples the sampling capacitor ( 710 ) to the input terminal of the first gain stage ( 110 ) when the first sampling switch ( 720 ) couples the sampling capacitor ( 710 ) to the output signal (Vout).
