In one example embodiment, a programmable capacitor array is provided for low distortion and minimizing linearity degradation of an input (Vin) by utilizing control circuitry to switch on and off an array of MOSFET switches. The control circuitry turns on a MOSFET to load a capacitance on Vin and turns off the MOSFET to remove the capacitance from Vin in response to a Din control signal. When the intention is to load Vin with the capacitance, the MOSFET is left on continuously. When the intention is to remove or unload the capacitance from Vin, the MOSFET is primarily turned off, however, the MOSFET is still periodically turned on with appropriate voltage levels in response to a clock signal for periods of time when the loading of the capacitance on Vin is tolerable to the system, thereby ensuring minimal linearity degradation of Vin due to the programmable capacitor array system.
