System and method for reducing effects of switched capacitor kickback noise

A circuit, comprising:

• a first input terminal;
• a first transmission line;
• a first sampling switch coupled to the first input terminal through the first transmission line, wherein the sampling switch comprises an NMOS gate;
• a first sampling capacitor coupled to the sampling switch;
• and
• a first open-circuit quarter wavelength stub coupled to the first transmission line, the first open-circuit quarter wavelength stub configured to reduce kickback noise on the first transmission line.

A method for reducing kickback noise in a circuit, comprising:

• determining a frequency associated with a kickback noise on a first transmission line of the circuit, the circuit having an input terminal coupled to the first transmission line;
• configuring a length of an open-circuit quarter wavelength stub to correspond to the determined frequency;
• and
• coupling the open-circuit quarter wavelength stub to the first transmission line to filter the frequency associated with the kickback noise, wherein the kickback noise is resulted from opening a sampling switch in the circuit.
