A Fully Integrated CMOS VCO for DCS-1800 Direct Conversion Receivers

The goal of this article is to prove that restrictive phase noise requirements can be achieved with a fully integrated CMOS VCO if the LC tank circuit is properly designed. The VCO has been designed in a standard two-metal layer process with 0.8 mm CMO...
The growing demand for mobile communications, mainly telephony, implies the need for better performance of RF transceiver architectures. A fundamental element in these front-ends is a voltage-controlled oscillator (VCO), the performance of which is a determining factor related to system limitations. Fully integrated VCOs usually suffer from poor phase...
