Abstract
This paper presents a low power, high gain low noise amplifier (LNA) design using current re-use inductors and complementary MOS structure. Gain variability has been achieved using forward body bias technique applied in the amplifying transistor. Using current re-use inductors at the drain of the complementary MOS structure, drain current is shared between PMOS and NMOS. The width of amplifying transistor is chosen to give minimum noise figure and good input matching. The observations show that the gain obtained by the proposed structure is 8.05dB with low noise figure of 2.14dB. The supply voltage used in the LNA design is 1.1V resulting in a power consumption of 2.607mW.
