WebAug 10, 2012 · An optional series resistor can be placed in the circuit to create a low-pass filter, attenuating high-frequency noise on the signal. The sampling will then be performed exclusively by manipulating the input/output ports and the ADC. STEP 1: PRECHARGE THE CAPACITORS Two capacitors are charged to opposite voltages.
WebJul 27, 2007 · When the switches are configured in position 1, the samplingcapacitor is charged to the voltage of the sampling node, in this case V S .The switches are then flipped to position 2, where the accumulatedcharge on the sampling capacitor is transferred to the rest of thesampling circuitry. The process then begins all over again.
