This paper describes the design of a differential class-E PA for Bluetooth applications in 0.18µm CMOS technology with load mismatch protection and power control features. The breakdown induced by load mismatch can be avoided by attenuating the RF power to the final stage during over voltage conditions. Power control is realized by means of "open loop" techniques to regulate the power supply voltage, and a novel controllable bias network with temperature compensated is proposed, which allows adoi:10.1109/iciea.2009.5138240 fatcat:gcwbhe2vxrdbvewn4faurnsoze
