Abstract
CMOS power amplifiers (PAs) are disclosed having one or more integrated one-time programming (OTP) memories that are utilized to control at least in part operation of the CMOS PAs. The integrated OTP memories within the CMOS power amplifiers (PAs) allow adjustments, such as one-time factory trimming, of CMOS PA integrated circuits to optimize or improve performance. With this capability, for example, the tuning and biasing of stages within a multi-stage amplifier within a CMOS PA can be measured during factory test and adjusted by setting one or more bits in the OTP memories, as desired. Further, the operation of other circuitry within the PA can also be controlled at least in part with parameter settings stored in the OTP memories.
