Abstract
This paper presents a study of the design of a 300-MHz voltage-controlled oscillator (VCO) implemented in a 0.5-μm Silicon-On-Sapphire (SOS) CMOS technology. The circuit is designed for use in a frequency synthesizer in a high-temperature (200°C) transceiver. Several issues relating to high-temperature applications as well as the overall system architecture are presented. The design of the VCO is emphasized in this paper, but a programmable divider, phase detector/charge pump and loop filter were also designed for use in closed-loop tests of the VCO and will also be briefly discussed. Prototyping and testing procedures are discussed and the results of the prototyped circuits are evaluated.
