LC-Oscillator for 94 GHz Automotive Radar SystemudFabricated in SiGe:C BiCMOS Technology

摘要

This paper presents the design and measurement of a voltage-controlled oscillator (VCO) for the use in a 94 GHz automotive radar system and other applications.udThe oscillator has been fabricated in a 200udGHz SiGe:C BiCMOS technology with 0.25 µm minimumudfeature size. The oscillator is fully integrated on a singleudchip with a chip area of only 0.25 mm2.udThe fabricated oscillator has a tuning range of 2.2 GHzudand a supply voltage of -3 Volt.
