A 1.2V, 0.7mW of Low Noise Amplifier for WSN Band

WSN is a sensor network to monitor various environment and physical background such as temperature, pressure, sounds etc. that are used to pass data from source to sink and data can be read from the sink. Sensor networks consist of various nodes each node can communicate with each other with radio signals. Every node has a good transceiver to receive and transmit these radio signals.This paper describes the work of designing a low noise amplifier, which is first stage in a receiver. In this paper A Common Source inductive generation LNA is designed with 180nm Technology at 1.2V for WSN Band, i.e. at 2.4GHz as operating frequency which has gain of 18.53dB and noise figure of 1.60dB, consumes power of 0.78mW.
