Most low noise amplifier designs focus on eliminating sources of noise that are intrinsic to the amplifier (thennal noise, Ilfnoise). As integrated drcuit design moves increasingly towards mixed signal implementations, the design of low-noise analog amplifiers must be re...evaluated to consider the switching noise generated by on-<:hip digital circuitry. We designed three fully differential ver...

In this paper, reduced power consumption, low-noise CMOS amplifier using chopper technique is designed, chopper-equalized amplifier had been used as a front end of a voltage-to-frequency converter instrument which performs pretty well, and they were meeting just about every specification, but they had a problem with undesired and unpleasant little offset shifts and jumps. Trying to solve this p...

This paper presents measured results of manmade noise impact on an cryogenic receiver front-end (CRFE) in urban and suburban areas in the 2-GHz band with amplitude probability distribution (APD). The CRFE comprises a high-temperature superconducting filter, cryogenically-cooled low-noise amplifier, and highly-reliable cryostat. The CRFE is expected to be an effective and practical approach to a...

This paper introduces wideband low noise amplifier design for Long Term Evolution systems. The three-stage, cascade wideband low noise amplifier structure will be presented. The low noise amplifier (LNA) is design for uplink channels for LTE systems. The LNA is designed for LTE receiver front-end which operates in 700-1300 MHz frequency range, covering almost entire LTE uplink frequency band. W...

This paper presents a single current controlled current conveyor trans-conductance amplifier (CCCCTA)based multi-input single output (MISO) voltage-mode universal biquad filter. The proposed filter employs only single CCCCTA, two capacitors and one permanently grounded resistor. The proposed filter realizes all the standard filter functions i.e. low pass (LP), band pass (BP) and high pass (HP),...

this paper proposes a low voltage (±0.55v supply voltage) low power (44.65µw) high common mode rejection ratio (cmrr) differential amplifier (d.a.) with rail to rail input common mode range (icmr), constant transconductance (gm) and enhanced frequency performance. its high performance is obtained using a simple negative averaging method so that it cancels out the common mode input signals at th...

Low noise amplifier is the front end block of radio-frequency receiver system. Its design required various characteristics such as power gain, noise figure, insertion losses and power consumption. In this paper we have proposed a single stage low noise amplifier design with high gain and low noise using inductive source degeneration topology for frequency range of 3 GHz to 7 GHz and also use th...
