ABSTRACT:
A method of selecting component values for an analog circuit includes identifying a cost function that evaluates similarity between an approximate frequency response function and a preferred frequency response function for at least one characteristic of the functions, determining the approximate frequency response function of the analog circuit based on an approximate component value, and changing the approximate component value based on a determined magnitude of similarity between the preferred frequency response function and the approximate frequency response function for the at least one characteristic. An impedance matching apparatus includes a mismatch detection circuit that produces a difference between source and load impedances, a match network controller that produces a control value based on the difference, and a reconfigurable varactor match network including at least one stub mounted varactor having a capacitance controlled by the control value to match the source and load impedances.
