Abstract
A tunable inductor circuit and phase tuning circuit utilizing a tunable inductor circuit for dynamically controlling signal phase delay in RF/Microwave Circuits and related applications. The tunable inductor includes an inductor and a voltage variable capacitor connected to each other. The tunable inductor and voltage variable capacitor can be connected to each other in parallel or in series. The phase tuning circuit includes at least one tunable inductor circuit and at least one voltage variable capacitor coupled to the at least one tunable inductor circuit, wherein the at least one tunable inductor circuit and the voltage variable capacitor are responsive to control signals to alter a tuning characteristic of the phase tuning circuit.
