ABSTRACT:
A constant current bias circuit and associated method is disclosed. The constant current bias circuit comprises an output stage for amplifying a radio frequency (RF) signal, wherein the output stage is operably coupled with a voltage. The constant current bias circuit further comprises a bias circuit operably coupled with the output stage for generating a substantially constant current bias to the output stage. The constant current bias circuit still further comprises a plurality of bias transistors operably coupled with the voltage and the output stage.
