Abstract :
In this paper, a novel circuit topology of low-noise amplifiers suitable for multi-band and multi-standard wireless applications is proposed. By employing a broadband input matching technique and vactors in the inter-stage and output matching networks, a compact LNA with continuous frequency tuning capability is realized. The proposed circuit is implemented in a standard 0.18-mum CMOS technology. Based on the measurement results, the LNA can operate from 2.9 to 3.5 GHz with a forward gain of 9plusmn3 dB while consuming a dc power of 18 mW from a 1.8-V supply
