نویسنده
چکیده
This paper reports an area-efficient LNA design using an active inductor which can be realised in various UHF band receivers. The overall low noise performance of LNA is achieved by cancelling the inductor noise through additional feed forward path. This circuit is implemented using 0.18μm CMOS technology with cadence environment and its operating range is 0.4 to 1GHz. Design is simulated in virtuoso simulator and simulation results are measured. Noise figure is 1.6 to 3.0 dB for the UHF band and power dissipation of overall circuit is 14.03mw at 1.8V supply. KEYWORD: Cadence, MOS based Active Inductor, Feed forward path logic (FFP), Low Noise Amplifier (LNA), Spectre Simulator.

Narrow band Low Noise Amplifiers (LNA) use inductors for band selection and input matching to reduce power consumption and reduce thermal noise generation. The LNA amplifies all signals within its fixed band, including blocking signals. This requires a larger dynamic range from the rest of the front end (mixers and analog to digital converters (ADC)).

This paper presents a new variable gain low noise amplifier (VG-LNA) for ultra-wideband (UWB) applications. The proposed VG-LNA uses a common-source (CS) with a shunt-shunt active feedback as an input stage to realize input matching and partial noise cancelling. An output stage consists of a gain-boosted CS cascode and a gain control circuit that moves the high resonant frequency to higher freq...
