Abstract
A radio frequency (RF) power detector includes a first circuit having a first rectifying diode with a first terminal coupled to a first power supply voltage node. The first circuit also includes an input terminal coupled to a second terminal of the first rectifying diode, a first transistor having a first collector coupled to the second terminal of the first rectifying diode and a first emitter coupled to a reference voltage node, and a second transistor having a second emitter coupled to the reference voltage node and a second collector coupled to a second power supply voltage node. The first circuit further includes a low-pass filter network coupled between a first base of the first collector and a second base of the second transistor, and a first output terminal coupled to the second collector of the second transistor.
