So far published CMOS log-amps fail to demonstrate accurate performance over temperature. This thesis present a temperature compensated CMOS RF power detector based on the log-amp architecture with an industry temperature range of -40 C to 84 C. Up to 900 MHz the temperature drift is never larger than +/-1.1 dB for all 24 measured samples over the temperature range. The prototyped IC has an active area of 0.76mm^2 and draws 6.3mA from a 1.8V power supply. Simulations of newer CMOS technologies show that this IC would compete in all important specifications for 65 nm technology. A new temperature compensation scheme was invented. In simulations the temperature drift for RF input signals up to 900 MHz is limited to 0.8 dB.
