Adaptive Enhancement of Low Noise Amplifier Using Cadence Virtuoso Tool

This paper mainly focuses on low power based amplifier (LNA) design. These types of amplifier design are suitable for low power wireless applications. Here different types of low noise amplifier designs are considered for designing a front end receiver. LNA is used for impedance matching, amplify weak signal and eliminate the unwanted noise signal. Selecting proper circuit element, this delivers better output and prevent short circuitry. Noise cancellation technique, which eliminates unwanted signals are present in the incoming signal. Common gate, resistive parallel feedback and cascading feedback network are designed for low power. Transient analysis and AC analysis are used for calculating the power consumption and the bandwidth respectively. Using current reuse circuit, this enables the generation of necessary current to the design. Cadence analog library is used for designing a low noise amplifier in 180nm technology.
