Design of cascaded narrow band low noise amplifier

LNA (Low noise amplifier) is very important block in frontend design of RF components. Gain of the transceiver is mainly dependent on the gain of first RF component i.e LNA, this can be studied using Frii's formula. In the paper an approach for design of narrow band cascaded and cascoded Low Noise Amplifier with inductor source degenerated technique is presented. 2.45 GHz is the Radio frequency used for this design(ISM band). The circuit is designed to have a gain of 17.22dB and power consumption of 4mW. This is validated in Cadence Virtuoso Tool using 180 nano-meter technology CMOS process with lvolts of power supply. The circuit is designed for wireless body area network applications.
