Abstract: Examples provide a method of performing automatic gain control (AGC) in a wireless receiver, the method including computing, by an energy detection (ED) circuit, a variance in an output signal of an analog-to-digital converter (ADC), and activating, by the ED circuit, an AGC circuit to adjust a gain of at least one component in a radio frequency integrated chip (RFIC) in response to the variance exceeding a threshold. Examples also provide for a wireless receiver that implements such a method.

Abstract: A sliding intermediate frequency (IF) receiver and a sliding IF reception method are provided. A first local oscillation signal and a second local oscillation signal may be generated, based on a division ratio of a frequency of the first local oscillation signal to a frequency of the second local oscillation signal that is determined in advance so that an amount of power to be consumed or an error rate of the sliding IF receiver is optimized. A received input signal may be converted to a first IF signal, based on the first local oscillation signal, and the first IF signal may be converted to a second IF signal, based on the second local oscillation signal.

Abstract: Provided is a method and an apparatus to calibrate an output of an oscillator. The method includes calibrating the output frequency of the oscillator to be a predetermined frequency. The method also generates a differential signal corresponding to the calibrated frequency, and operates the oscillator in response to the differential signal. The oscillator is controlled by the differential signal to remove common mode noise.
