Characterization of CMOS Impedance Tuning Unit

Abstract
The use of reconfigurable matching has become more and more desirable as mismatches between such interfaces as antenna and receiver increase. The present paper investigates reconfigurable matching by measurements of a CMOS Impedance Tuning Unit (ITU) designed for Digital Video Broadcasting for Handheld devices (DVB-H). The ITU consists of switched capacitors arranged in three capacitor banks, with inductors between them, thus creating a reconfigurable ladder matching network. It is demonstrated that any mismatch up to VSWR = 8 can be transformed to a mismatch better than VSWR = 2, that IIP2 = 7 dBm and IIP3 = 0.5 dBm, and that loss is 2.1 dB.
