Small VCO-Gain Variation Adding a Bias-Shifted Inversion-Mode MOS Varactor

This letter proposes a small voltage-controlled oscillator (VCO)-gain variation (AKVCO) technique using the capacitance-slope change of the varactor, which is achieved by adding a bias-shifted inversion-mode MOS varactor in parallel with a conventional accumulation-mode MOS varactor. This technique...
