Abstract

A phase noise and spur filtering technique suppresses the phase-noise contribution to the receiver noise figure in the presence of a -15 dBm blocker by 25 dB consuming only 8 mA, bridging the performance gap between ring oscillators and LC-oscillators. The technique breaks the conventional trade-off between power and phase-noise in oscillators. It makes use of the symmetry of phase noise around the carrier by using the image of the reciprocal-mixing at double the blocker beat frequency to cancel noise in the receive-band.
