Abstract:
A system for processing a signal is provided. The system includes a differential amplifier receiving a radio-frequency input signal at a first differential input. A rectifying device such as a transistor has a control terminal that is coupled to an output of the differential amplifier and an output that is coupled to a second differential input of the differential amplifier. The second differential input of the differential amplifier receives a low frequency feedback signal from the output of the rectifying device, such as by damping the frequency response at the output of the rectifying device using a capacitor and a current source coupled to the output of the rectifying device.
