closed/open. When S1/S2 are closed & S3 is open, one input of the sample and hold circuit moves to (V
the other charges to the analog input voltage. When the switches are flipped, the charge on C1 and C2 are averaged via S3, with
the result that a single-ended analog input is switched to a differential voltage centered about (V
switch on every cycle of the ADC clock (open one-half ADC clock, closed one-half ADC clock). There are additional
capacitances associated with the analog input pad, routing, etc., but these do not filter into the S/H output voltage, as S1 provides
isolation during the charge-sharing phase. One aspect of this circuit is that there is an on-going input current, which is a function
of the analog input voltage, V
