Abstract :
An integrated RF power detector used in wireless communication is presented. The detector uses a unique replica circuitry to compensate for any changes in process or temperature. This results in a high degree of accuracy and a higher dynamic range. The detector has more than 25 dB of dynamic range within +/- 0.5 dB accuracy and is placed in the die along with the power amplifier in a BiCMOS process. The detector runs up to 7 GHz in simulation, though it is tested at 2.4 GHz here. It runs of a 3 V supply and consumes less than 5 mA.
