A 0.8 dB NF ESD-protected 9 mW CMOS LNA

The GPS L2 band, centered at 1.2276 GHz, is planned to enhance the capabilities of civil GPS to backup the conventional GPS L1 link. As the L2 receiver is required to detect a low power signal, an LNA with extremely low noise figure is required. In addition, the LNA must exhibit a large gain to suppress noise from the subsequent stages. This ESD-protected CMOS LNA meets these requirements.
