Abstract—A wideband radio-frequency (RF) power detection
system is presented. The detection technique uses NMOS devices
operating in the triode regime to generate an average current pro-
portional to RF input power; this current is converted to voltage
and amplified using a piecewise linear logarithmic approximation.
Optimization of the NMOS devices is discussed, and a method
of gain control is proposed for compensation of temperature and
process variation. The power detector o
