Apparatus for radio-frequency receiver with in-phase/quadrature calibration and associated methods

Abstract:

An apparatus includes a radio-frequency (RF) receiver. The RF receiver includes an analog-to-digital converter (ADC) to convert an analog input signal to a digital output signal in response to an ADC clock signal. The RF receiver further includes a frequency generator to selectively provide either a clock signal to be provided as the ADC clock signal or a signal to be used for in-phase-quadrature (IQ) calibration of the RF receiver.
