A low‐voltage and low‐power current‐mode winner‐take‐all (maximum) circuit
Electronics Letters, 2023 In this Letter, a new low‐voltage and low‐power current‐mode winner‐take‐all (WTA) circuit is proposed. The proposed circuit is able to operate with a low supply voltage requirement while exhibiting a high accuracy.

Mechanically Generating Entangled Photons from the Vacuum: A Microwave Circuit-Acoustic Resonator Analogue of the Unruh Effect [PDF]
Phys. Rev. A 99, 053833 (2019), 2018 We consider a model for an oscillatory, relativistic accelerating photodetector inside a cavity and show that the entangled photon pair production from the vacuum (Unruh effect) can be accurately described in the steady state by a non-degenerate parametric amplifier (NDPA), with the detector's accelerating center of mass serving as the parametric drive

Unconstrained evolution of close-to-ideal "LCR" low-pass filter [PDF]
The unconstrained evolution has already been applied in the past towards design of digital circuits, and extraordinary results have been obtained, including generation of more compact circuits with smaller number of electronic components.

Integrating 'atomistic', intrinsic parameter fluctuations into compact model circuit analysis [PDF]
, 2003 MOSFET parameter fluctuations, resulting from the 'atomistic' granular nature of matter, are predicted to be a critical roadblock to the scaling of devices in future electronic systems.

Analogue circuit of the inductive polarization resistance
Electrochimica Acta, 2011 [EN] The electrochemical techniques used to measure metallic corrosion rely on making a direct electrical contact to the working electrode. The inductive or non-contacting method is based in the application of an external electrical signal that does not need to make physical contact to the metal to polarize it.

Vacuum fluctuations and generalized boundary conditions [PDF]
, 2013 We present a study of the static and dynamical Casimir effects for a quantum field theory satisfying generalized Robin boundary condition, of a kind that arises naturally within the context of quantum circuits. Since those conditions may also be relevant

Modelling of the Fender Bassman 5F6-A Tone Stack [PDF]
arXiv, 2021 This paper outlines the procedure for the effective modelling of a complex analogue filter circuit. The Fender Bassman 5F6-A is a circuit commonly employed in guitar amplifiers to shape the tonal characteristics of the amplifier output. On first inspection this circuit may look rather simple, however the controls are not orthogonal, resulting in ...
