Noise model of the cryogenic nuclear magnetic resonance spectroscopy system's receiving chain

open access: yesAutomatika, 2022
One of the challenges in modern nuclear magnetic resonance (NMR) is achieving its highest possible measuring sensitivity. This is because modern NMR samples' response signals decrease, so background noise of the used NMR spectroscopy system causes bigger

Intrinsic noise induced resonance in presence of sub-threshold signal in Brusselator

open access: yes, 2011
In a system of non-linear chemical reactions called the Brusselator, we show that {\it intrinsic noise} can be regulated to drive it to exhibit resonance in the presence of a sub-threshold signal.

Generating All Two-MOS-Transistor Amplifiers Leads to New Wide-Band LNAs [PDF]

open access: yes, 2001
This paper presents a methodology that systematically generates all 2-MOS-transistor wide-band amplifiers, assuming that MOSFET is exploited as a voltage-controlled current source. This leads to new circuits.

Shot noise of Coulomb drag current

open access: yes, 2000
We work out a theory of shot noise in a special case. This is a noise of the Coulomb drag current excited under the ballistic transport regime in a one-dimensional nanowire by a ballistic non-Ohmic current in a nearby parallel nanowire.

Optimizing Low Noise Amplifiers: A Two-Stage Approach for Improved Noise Figure and Stability

open access: yesIEEE Access
This study introduces a new design for a low noise amplifier (LNA) consisting of two stages taking advantage of the inherent lossy properties of the input matching components. By doing this, the design balances the minimum noise figure (NF) and stability,

Coherence stabilization of a two-qubit gate by AC fields [PDF]

open access: yes, 2004
We consider a CNOT gate operation under the influence of quantum bit-flip noise and demonstrate that ac fields can change bit-flip noise into phase noise and thereby improve coherence up to several orders of magnitude while the gate operation time ...
