Abstract :
A 2GHz mean-square power detector with integrated chopper is presented. It typically achieves an offset reduction of 14.8dB compared to un-chopped, untrimmed units and 12dB reduction of the offset variation overtemperature (-40°C to +85°C) compared to laser-trimmed units. The chip is designed in a 0.35 μm BiCMOS process, measures 1.5×1.5mm2 and draws 8mA from a 2.7V supply.
