Abstract
A power detector constituted of: a transconductance element arranged to output a rectified detection current, the magnitude thereof arranged to increase exponentially responsive to a linear increase in the amplitude of an input signal; and at least one p-n junction based device, a function of the rectified detection current arranged to flow there through. The output of the power detector is a function of the voltage across the at least one p-n junction based device.
