Abstract
Systems, devices, and techniques for performing peak detection are described. A described receiver includes a first amplifier to amplify an input signal to generate a first amplified signal; a mixer to downconvert the first amplified signal to generate a downconverted signal; a second amplifier to amplify the downconverted signal to generate a second amplified signal; a filter, being selectably engageable by the receiver, a peak detector configured to perform voltage measurements of the second amplified signal; and switch circuitry. The switch circuitry is configured to selectably disengage the filter during a first measurement phase during which a first voltage measurement performed by the peak detector is indicative of an output voltage swing of the first amplifier, and to selectably engage the filter during a second measurement phase during which a second voltage measurement performed by the peak detector is indicative of an output voltage swing of the second amplifier.
