抄録

24-GHz low noise amplifier (LNA) and voltage controlled oscillator (VCO) in 0.25-μm SiGe BiCMOS technology were developed to create low-cost radio frequency (RF) modules for short-range ultra-wideband radar systems. A two-stage shunt-feedback LNA that used inductive biasing had a -3-dB bandwidth of 11.4 GHz, a noise figure of 3.8 dB at 24 GHz, and a group delay deviation within 21 ps (from 10 GHz to 30 GHz). The LC-tuned differential VCO, with a high quality-factor center-tapped inductor design, oscillated at 24 GHz with phase noise of -100 dBc/Hz at 1 MHz offset. The VCO core consumed only 2 mA of current.
