An Asymmetrical Double-Gate VCO with Wide Frequency Range Conference Paper

abstract

• Independently-controlled double-gate devices using asymmetrical (n+/p+) gates are applied to the design of a novel VT-controlled voltage controlled oscillator (VCO). The VCO supports high operating frequencies and a wide tuning range. The back gates of the asymmetrical double-gate devices are used to modulate the threshold voltages of the front gate devices. A two-fold frequency tuning range is observed without the complexity of additional devices, resulting in improved performance, noise immunity, and power efficiency over conventional well/body bias techniques. These results are validated through mixed-mode MEDICI simulations. 2006 IEEE.
