Abstract
Here in this paper the design of a low power low noise amplifier (LNA) is presented which works for very wideband of frequency known as UWB signals. This method uses current reused technique which helps in reducing the power consumption while maintaining the same conversion gain and NF. No inductor is used in this circuit which reduces the complexity. Here a power gain of 12.6 dB, a NF of 2.1 dB at 3.5 GHz and 8.5 GHz is achieved, while consuming very less power nearly 7.6mW. It is clear from the observations that this technique solves the major problem of power consumption that was present in the previously existing techniques.
