A fully integrated 1 V 5.8 GHz bipolar LNA

This paper describes a low voltage low noise amplifier design in a 0.5 /spl mu/m bipolar process, targeting a center frequency of 5.8 GHz with a voltage supply of 1 V. The forward transmission S/sub 21/ is 11.5 dB at a low power consumption of 6.6 mW, including all biasing circuitry. The overall noise figure of the LNA is 4 dB with both input and output impedances matched to 50 ohm. The circuit uses no off-chip components, such as bonding wires and biasing-tees, which makes it suitable for robust integration.
