Abstract :
In this paper, a variable band structure which can be used for wireless front-end circuits is proposed. Based on this structure, a single-ended one-stage cascode low noise amplifier (LNA) is presented for future multi-band and multi-standard wireless applications. A band selective performance is achieved by utilizing a varactor at the output matching circuit. The LNA implemented in 0.25 mum BiCMOS technology achieves 9-12 dB gain from 0.7 to 1.4 GHz consuming 7mA with 2.5 V voltage supply
