IEICE transactions on fundamentals of electronics, communications and computer sciences, E81-A(2) 224-229, Feb, 1998 Peer-reviewedThis paper proposes a novel broad-band MMIC VCO using an active inductor. This VCO is composed of a serial resonant circuit, in which the capacitor is in series with an active inductor that has a constant negative resistance. Since the inductance value of this active inductor is inversely proportional to the square of the transconductance and can vary widely with the FETs' gate bias control, a broad-band oscillation tuning range can be obtained. Furthermore, since this active inductor can generate a constant negative resistance of more than 50 Ω, the proposed VCO can oscillate against a 50-Ω output load immediately without using additional impedance transformers. We have fabricated the VCO using a GaAs MESFET process. A frequency tuning range of more than 50%, from 1.56 to 2.85 GHz, with an output power of 4.4±1.0 dBm, was obtained. With a carrier of 2.07 GHz, the phase noise at 1-MHz offset was less than -110 dBc/Hz. The chip size was less than 0.61 mm^2, and the power consumption was 80 mW. This broad-band analog design can be used at microwave frequencies in PLL applications as a compact alternative to other types of oscillator circuits.

John Wiley & Sons, Inc., Mar, 2005 (ISBN: 9780471270539)RF and Microwave Engineering is one of the fastest growth areas of the past decade and will probably continue to be a very active area of research and application in a large variety of fields. The six volume set of Encyclopedia of RF and Microwave Engineering illustrates how this field has been the key to enabling technology responsible for the phenomenal growth of wireless communications. This set also examines how RF and microwave engineering continues to have great influence as the technology behind such important applications as radar, remote sensing, remote control, sensors, navigation, surveillance, electronic warfare, radiometers, plasma research, and imaging.
