| Abstract(in English) | In accordance with the rapid increase of operation frequencies of CMOS circuits, radio-frequency system-on-a-chip (RF-SOC) that integrates GHz-RF circuits and large-scale digital circuits becomes a key devices for wireless systems and high speed networks. To develop high performance RF-SOC, high quality PLL (Phase-Locked -Loop) in the presence of cross talk noise generated by high-speed and large-scale digital circuits are required as oscillators or clock generators. We designed a test chip including a proposed differential input VCO, CMOS logic circuits and substrate noise detectors using a 0.25um CMOS technology, and measured characteristics of output jitter of the VCO to investigate the effect of the substrate crosstalk noise. As a result, the proposed differential input VCO is high tolerance for low-frequency noise in comparison with a conventional single-input VCO. |
