Abstract
A circuit with a sampling network may include a pair of capacitors, where each of the capacitors has a first node and a second node; a first pair of switches communicatively coupling corresponding differential input voltage signals to the first node of each of the capacitors; and a second pair of switches communicatively coupling the second node of each of the capacitors to a common mode voltage source. Corresponding differential output voltage signals at the second node of each of the capacitors may be communicatively coupled using a differential switch. The second pair of switches may be coupled in parallel with the differential switch. A clock signal of the differential switch may be de-asserted prior to de-asserting corresponding clock signals for each of the second pair of switches.
