Original Abstract Submitted
Aspects of the present disclosure provide an integrated circuit (IC). The IC comprises oscillator systems each configured to generate a respective oscillating signal. The IC comprises signal paths each coupled to a respective one of the plurality of oscillator systems, a first one of the plurality of signal paths comprises a mixer, and another one comprises a tone generator. The tone generator is configured to generate a tone signal based on the oscillating signal from the corresponding oscillator system. The mixer is coupled to the tone generator of said another one of said plurality of signal paths and is configured to generate a mixed signal for RSB calibration based on the tone signal from the tone generator of said another one of the plurality of signal paths and the oscillating signal from the oscillator system coupled to said first one of said plurality of signal paths.
