Abstract
A variable capacitor for integrated circuits used as a decoupling capacitor that operates at both low and high frequencies is disclosed. Based upon a programmable input signal, the decoupling capacitance of the circuit varies within a specific range providing a vehicle for testing decoupling capacitance requirements of new integrated circuits and functions and new silicon processes. The programmable input signal switches a transistor from the saturated region of operation to the unsaturated region of operation, varying the decoupling capacitance of the transistor. By providing circuitry to control the switching of the transistor, the circuit operates at both low and high frequencies, reducing the negative impacts of transistor channel resistance during high frequency operation.
