Abstract :
The first active impedance matching circuit for RF applications is introduced. It adapts arbitrary output impedances to values between 50 and 250 Omega, from 0 to 5 GHz, and occupies only 0.005 mm2 in 0.35 mum SiGe-BiCMOS. It is vastly superior to traditional passive-element solutions by being: the first flexible matching circuit to adapt any impedance to any desired value; the smallest matching circuit ever; and a rare example of wideband matching. Application to a low-noise amplifier proves the potential of the new circuit
