Abstract

A particular device includes a replica circuit disposed above a dielectric substrate. The replica circuit includes a thin film transistor (TFT) configured to function as a variable capacitor or a variable resistor. The device further includes a transformer disposed above the dielectric substrate and coupled to the replica circuit. The transformer is configured facilitate an impedance match between the replica circuit and an antenna.
