Abstract

An integrated circuit is described herein. According to one or more embodiments, the integrated circuit includes a local oscillator with a voltage-controlled oscillator (VCO) that generates a local oscillator signal. Further, the integrated circuit includes a frequency divider coupled to the VCO downstream thereof. The frequency divider provides a frequency-divided local oscillator signal by reducing the frequency of the local oscillator signal by a constant factor. A first test pad of the integrated circuit is configured to receive a reference oscillator signal. Further, the integrated circuit includes a first mixer that receives the reference oscillator signal and the frequency-divided local oscillator signal to down-convert the frequency-divided local oscillator signal.
