Fecha de publicación: | 2012 | Editor/a: | 0020-7217 | Publicación seriada: | International Journal of Electronics | Resumen: | This article presents a wide range inductance–capacitance voltage controlled oscillator (VCO) with a unit cells-based varactor. The unit cell represents the minimum possible integrated varactor based on p–n junction diodes, where N+ diffusions are central rectangles, surrounded by doughnut shaped P+ diffusions, with their respective contacts. The varactors are designed using the AMS 0.35 µm BiCMOS process. A physical model has been derived from the measurement of a set of eight fabricated varactors. Measurements indicate that the VCO, which is intended to be used in DVB-H, oscillates from 1.087 to 2.032 GHz, with a 61% tuning range. The phase noises of −124 dBc/Hz at 1 MHz offset and −108 dBc/Hz at 100 kHz offset are obtained | URI: | http://hdl.handle.net/10553/43593 | ISSN: | 0020-7217 | DOI: | 10.1080/00207217.2011.651699 | Fuente: | International Journal of Electronics[ISSN 0020-7217],v. 99, p. 1165-1178 |
