摘要： In this invention a single additional capacitor is added to a tuned cascode LNA which boosts the circuit Q and the gain of the amplifier. The added capacitor creates a negative real part of the impedance which when combined with the impedance of the LC tank circuit improves both the Q and the gain of the amplifier. The capacitor does not dissipate any power, and being a passive device the capacitor does not add additional noise to the circuit. With an improved gain there is a much improved signal to noise ratio. The higher Q allows the amplifier to provide some additional bandpass and reduce image reduction requirements in subsequent amplifier stages.

摘要： A new MOS varactor device is described. A bottom electrode comprises a plurality of diffusion junctions in a semiconductor substrate. The semiconductor substrate may be n-type or p-type. The diffusion junctions are arranged in a two-dimensional array. The diffusion junction may be either n-type or p-type. The diffusion junctions may be contained in a p-well or an n-well. A dielectric layer overlies the semiconductor substrate. A top electrode overlies the dielectric layer. The top electrode comprises a single polygon containing a two-dimensional array of openings therein that exposes the diffusion junctions. The top electrode preferably comprises polysilicon. An interlevel dielectric layer overlies the top electrode and the diffusion junction. The interlevel dielectric layer has a two-dimensional array of contact openings that expose the underlying diffusion junctions. A patterned metal layer overlies the interlevel dielectric layer and contacts the diffusion junctions through the contact openings.
