A Fully Reconfigurable Software-Defined Radio Transceiver in 0.13μm CMOS

A fully reconfigurable SDR contains an RX, a TX, and 2 synthesizers for true multi-standard operation. A MEMS-enabled dual-band LNA proves the feasibility of switched antenna filtering for interference robustness. The baseband section is programmable in noise level and in bandwidth from 350kHz to 23MHz. The receiver has 6dB NF, -9dBm IIP3, and up to 90dB gain. Implemented in a 0.13μmum CMOS process, it draws 62mA to 120mA in RX mode and 56mA to 89mA in TX mode from a 1.2V supply.
