Abstract

A current reuse LNA using inductive degeneration topology operates under 0.9 V owing to a body effect feedback. Compatible with VLSI the architecture is available to cover from GPS to 802.11b band, including DCS 1800 and UMTS third generation mobile phone. Well suited to low power low voltage requirements its weak bulkiness dedicates it to SOC application. With a 2.2mW power consumption, this circuit provides a more than 10 dB gain at 2 GHz. Achieving 1.34 dB NF, the linearity is competitive despite the 0.9 V supply voltage, with -16 dBm ICP1 and -4.5 dBm IIP3.
