This paper presents a low power reconfigurable narrowband, concurrent multiband, wideband multimode LNA for multi-standard applications. Subthreshold region biasing, quality factor aware impedance matching, component sharing between different modes are employed. Input matching is unbounded from other performance parameter. Proposed LNA works in narrowband mode at 1.8GHz, 2.1GHz and 2.4GHz, dualband mode at 1.9GHz and 5.4GHz and in wideband mode 2-5GHz. The voltage gain varies from 11dB to 18dB, noise figure from 5.5dB to 8.5dB and CP1dB -9.2dBm to -17.4dBm over different modes, while consuming 1.8mW in narrowband and 3.84mW in other modes from 1.8V supply in UMC180nm CMOS process. © 2015 IEEE.
