Design of high gain, low power CMOS multi-standard LNA

RF front-end defines everything between antenna and IF stage-including filter, amplifier and mixer. Low Noise Amplifier is an important building block of wireless receiver. A single-ended multi-standard CMOS LNA is designed for reconfigurable applications. The design addresses GSM, GPS, WCDMA, UMTS and LTE frequency bands. Based on wideband input matching, the designed LNA covers all band of interest. For multi-standard aim, capacitive switching technique is used to select desired bands of interest. The design is implemented using 90nm CMOS technology, achieving a Voltage Gain more than 30dB, Noise Figure less than 5dB and IIP3 better than -5dBm. The LNA consumes 6.2mW power at supply of IV.
