An innovative technique for the biasing of power amplifiers (PAs) is presented that allows reduction of the DC power consumption, especially when the PA is operated at mid/low output power, without compromising the linearity at high output power level. The fully integrated adaptive biasing circuit, in 0.5 /spl mu/m BICMOS technology, senses the operating PA power and adjusts its quiescent current accordingly. The method is applied to a UMTS PA, resulting in a power consumption saving of about 70% when compared to conventional biasing solutions.
