The spread of COVID-19 has much in common with the behavior an electric circuit, which can be used to predict pandemic trends.

The paper reported the design and thorough analysis of a thin-film solar cell (TFSC) based on molybdenum disulfide (MoS2) with an integrated Copper(I) Oxide (Cu2O) hole transport layer (HTL), employing one-dimensional Solar Cell Capacitance Simulator (SCAPS-1D) software. By varying crucial parameters such as absorber thickness, doping density, bulk defect well HTL concentration, electron affini...

'HE authors of the present paper have recently described a method for the experimental determination of the disintegration curve of Tnesotrons and have given a preliminary account of the results obtained. ' The method has been since improved and a new and more extensive set of data has been taken. A summary of the riew results is presented here. The experimental arrangement, which is similar in...

A technique is introduced to enable the simulation of floating-gate transistors within standard analogue circuit simulators, such as SPICE. This technique can be used in all types of circuit simulations, ranging from DC sweeps to charge-modification scenarios. The technique is then used to simulate several analogue circuits, the results of which show strong agreement with identical circuits fab...

The basic properties of programmable analogue arrays are described and the problem of quantifying the fitness of an analogue circuit is discussed. A set of blocks appropriate for use in an evolutionary algorithm is described and results presented showing how an evolutionary algorithm using these blocks can learn to produce a given input-output characteristic. Finally an example is presented sho...

Various measurement and control systems use magnetic or optical encoders that transform linear displacement and other physical quantities to an analogue quadrature signal. In this paper, we study the problem of, how to accurately delay the analogue quadrature signals in the Sin/Cos encoders within the range of ±10° with the circuit that is potentially integrable on a single chip. Such precision...

Most analogue systems are designed manually because automatic circuit synthesis tools are presently available for only a limited range of design problems. This paper presents a new approach to circuit synthesis based on Genetic Algorithms. Using this method it is possible in principle to synthesize circuits to meet any linear or non-linear, frequency-domain or time-domain, specification. When a...

Gillian Marshall and Steve Collins DRA Malvern, UK INTRODUCTION In this paper we describe an analogue VLSI circuit which implements the Radial Basis Function (RBF) algorithm, based around a compact Euclidean Distance calculator. A prototype chip has been fabricated and tested. First, we describe the RBF architecture and present results from the test chip. We then discuss the impact of device va...
