Abstract
Adjustable circuit components may be formed from arrays of differential circuit elements such as differential capacitors and differential current sources. The differential circuit elements may each have a control input. The differential circuit elements in each array of differential circuit elements may be connected in parallel between first and second terminals. A thermometer code control signal may be provided to the control inputs to adjust the capacitance, current, or other parameter associated with the adjustable circuit component. Adjustable circuit components may also be formed from an array of capacitors or other circuit elements having successively increasing strengths.
