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...

A highly selective impedance transformation filtering technique suitable for tunable selective RF receivers is proposed in this paper. To achieve blocker rejection comparable to SAW filters, we use a two stage architecture based on a low noise trans-conductance amplifier (LNTA). The filter rejection is captured by a linear periodically varying (LPV) model that includes band limitation by the LN...

UNLABELLED The nucleus has emerged as a key target for nucleomodulins, a family of effectors produced by bacterial pathogens to control host transcription or other nuclear processes. The virulence factor LntA from Listeria monocytogenes stimulates interferon responses during infection by inhibiting BAHD1, a nuclear protein involved in gene silencing by promoting heterochromatin formation. So fa...

A noise-canceling processor is developed for matched-field processing problems involving a signal buried in noise. This processor is based on modeling both signal and noise and searching the space of unknown parameters to achieve the best agreement between covariances. The noise-canceling processor educes to the Bartlett processor in the limit of high signal-to-noise ratio. The examples illustr...

Analog systems to achieve active noise cancellation in headphones were designed and implemented. Our project addresses two distinct technqiues feed forward and feedback systems. The work up to mid-semester, which was focused mainly on a feed-forward system with the motivation of developing a clip-on platform for generic earphones, is presented briefly. Limitations of this approach that lead to ...

Low Noise Amplifier, CMOS, Noise Canceling, Technique. This paper presents a 0.8V, 3.6GHz narrow band CMOS low noise amplifier (LNA). A current-reused technique is employed to increase the gain of LNA. Also, in order to achieve low noise figure, a noise canceling technique is used in the output stage. The high gain LNA was designed and simulated in 0.13 μm CMOS process. A gain of 27 dB at 3.6GH...
