A Co-design Study Of Filters And Oscillator For Low Phase ...
ABSTRACT⎯In this paper, we present a novel oscillator (OSC) design. Bandpass filters, which can suppress harmonics, are incorporated into a co-design with an OSC to improve the OSC phase noise and harmonic rejection. The proposed OSC/bandpass filter co-design achieves a phase noise of - ... Document Viewer
