A fully differential common-source cascode low noise amplifier(LNA) is presented for wireless receivers. The capacitive cross-coupling technique combined with cascode transistor is introduced to enhance LNA gain and reduce noise figure as well as the nonlinearity influence of cascaded transistors. A 2.6mm long on-chip folded dipole antenna is integrated with this LNA and co-design is performed for impedance conjugate matching and power transmission. The experimental results by ADS indicate that… CONTINUE READING
