Analogue Gravity on a Superconducting Chip [PDF]
, 2020 We describe how analogues of a Hawking evaporating black hole as well as the Unruh effect for an oscillatory, accelerating photodetector in vacuum may be realized using superconducting, microwave circuits that are fashioned out of Josephson tunnel junction and film bulk acoustic resonator elements.

Dependable Digitally-Assisted Mixed-Signal IPs Based on Integrated Self-Test & Self-Calibration [PDF]
, 2010 Heterogeneous SoC devices, including sensors, analogue and mixed-signal front-end circuits and the availability of massive digital processing capability, are being increasingly used in safety-critical applications like in the automotive, medical, and the

Advanced Engineering Materials, EarlyView.This study explores aerosol jet‐printed (AJP) surface roughness, its effects on the performance of microwave electronics, and its process contributors. First, an electromagnetic model is vetted for AJP's unique roughness signature. Simulations are built which show process‐induced roughness is as significant as conductor resistivity in driving microwave

Advanced Engineering Materials, EarlyView.Laboratory protocols for producing thin‐film pH electrodes for sterilized single‐use technologies have been successfully developed into a semiautomated workflow, with higher throughput and precision of membrane thickness. Accuracies are within 0.05 pH units versus ground truth, and uncertainty analysis reveals the largest sources of error to be derived

An experimental analogue for memristor based Chua's circuit [PDF]
arXiv, 2014 This paper presents the dynamics of a practical equivalent of a smooth memristor oscillator derived from Chua's circuit. This approach replaces the conventional Chua's diode by a flux controlled memristor with negative conductance. The central idea is to design a practical memristor based circuit using electronic analogy in order to bypass problems ...

Implications of Burn-In Stress on NBTI Degradation [PDF]
, 2015 Burn-in is accepted as a way to evaluate ageing effects in an accelerated manner. It has been suggested that burn-in stress may have a significant effect on the Negative Bias Temperature Instability (NBTI) of subthreshold CMOS circuits. This paper analyses the effect of burn-in on NBTI in the context of a Digital to Analogue Converter (DAC) circuit ...

Profilometry‐Based Indentation Plastometry Testing of Tungsten at High Temperature
Advanced Engineering Materials, EarlyView.Profilometry‐based indentation plastometry (PIP) allows extraction of stress‐strain curves from indent profiles. Tungsten is of industrial interest but is brittle at room temperature. It does plastically deform at higher temperatures. Excellent agreement is obtained between the two techniques in this regime, but PIP also gives plasticity ...

Ultra‐low line sensitivity and high PSRR sub‐threshold CMOS voltage reference
The Journal of Engineering, 2023 This paper presents a nanowatt CMOS voltage reference (VR) with ultra‐low line sensitivity (LS) and high‐power supply ripple rejection (PSRR). The proposed VR consists of two simple nanowatt two‐transistor (2T) VRs.
