This paper presents an analog VLSL circuit for implementation of Artificial Neural Networks (ANNs ). The building blocks of the proposed circuit include Differential voltage current controlled source (DVCCS), Super MOSFET and Differential voltage controlled voltage source (DVCVS) which are used to multiply incoming analog signals with variable weights, and current in / current out sigmoid funct...

Calculation of the design parameters current transformers (CTs) is very complex due to their magnetic and thermal properties, complexity structure, different ferromagnetic properties materials nonlinearity B-H curve core material. The secondary output these used for both measurement protection circuits. Therefore, AT's accuracy must be good precise. In this study, transformer modeled as 2D usin...

This paper proposes a low-current reference circuit for power-aware LSI applications. The circuit consists of two current generation subcircuits which are based on β-multiplier circuit, one with a positive and the other with a negative temperature coefficient. The variation of the reference current in a sample circuit designed to produce a current of 230 nA can be kept very small within ±1.3% i...
