Abstract
A radio frequency (RF) receive circuit is described herein. In accordance with one embodiment, the RF receive circuit includes a mixer configured to receive an RF input signal to down-convert the RF input signal into a base-band or intermediate frequency (IF) band, an analog-to-digital converter (ADC), and a signal processing chain coupled between the mixer and the ADC. The signal processing chain includes at least two circuit nodes. The RF receive circuit further includes an oscillator circuit that is configured to generate a test signal. The oscillator circuit is coupled to the signal processing chain and is configured to selectively feed the oscillator signal into one of the at least two circuit nodes.
