TECHNIQUE FOR CROSSTALK REDUCTION

摘要

A technique for cancelling or reducing crosstalk signals between controlled oscillators in an integrated circuit is provided. The technique involves an arrangement adapted to reduce a crosstalk signal generated by a first controlled oscillator to a second oscillator both comprised in the integrated circuit, wherein both controlled oscillators are configured to output a respective clock signal. The arrangement comprises a detector adapted to detect the crosstalk signal generated by the first controlled oscillator to the second controlled oscillator, a crosstalk cancellation circuit adapted to generate a cancellation signal having an amplitude substantially the same as that of the crosstalk signal and a phase substantially opposite to that of the crosstalk signal, and a cancellation signal injector adapted to introduce the cancellation signal into the second controlled oscillator.

1. An arrangement for reducing a crosstalk signal generated by a first controlled oscillator, CO, to a second CO both comprised in an integrated circuit, each CO adapted to output a respective clock signal, the arrangement comprising:
a first detector adapted to detect the crosstalk signal generated by the first CO to the second CO; a first crosstalk cancellation circuit adapted to generate a cancellation signal having an amplitude substantially the same as that of the crosstalk signal and a phase substantially opposite to that of the crosstalk signal; and a first cancellation signal injector adapted to introduce the cancellation signal into the second CO.
