Substrate noise generated by digital circuits on mixed-signal ICs can disturb the sensitiveanalog/RF circuits, such as Low Noise Amplifier (LNA), sharing the same substrate. This paperinvestigates the adverse impact of the substrate noise on a high frequency cascode LNA laid out on alightly doped substrate. By studying the major noise coupling mechanisms, a new and efficientmodeling method is p...

By Aalay Kapadia in Electrical Engineering and Electronic Engineering. The circuit topology we used for this project is a cascode LNA with inductive source. Typical parameters are maximum transducer gain, output power , low noise, circuit stability. Here a LNA is designed to obtain an optimum gain with minimum.

In this paper, a new design of concurrent dual-band Low Noise Amplifier (LNA) for multi-band single-channel Global Navigation Satellite System (GNSS) receivers is proposed. This new structure is able to operate concurrently at frequency of 1.2 and 1.57 GHz. Parallel and series resonance parts are employed in the input matching in order to achieve concurrent performance. With respect to used pse...

This paper presents the design and simulation of Low Noise Amplifier (LNA) in a 0.18μm CMOS technology. The LNA function is to amplify extremely low noise amplifier without adding noise and preserving required signal to noise ratio. Cadence design tool Spectre_RF is used to design and simulation based on resistors, inductors, capacitors and transistors. Power constrained methodology is used for...

This paper is based on analysis of a common source - common gate low noise transconductance amplifier (CS-CG LNTA). Conventional noise analyses equations are modified by considering to the low output impedance of the sub-micron transistors and also, parasitic gate-source capacitance. The calculated equations are more accurate than calculated equations in other works. Also, analyses show that th...
