This article proposes two topologies of voltage-mode and current-mode improved Wheatstone bridges. The features of the propose configurations are that: they can control magnitude of output signals via the input bias current; the proposed circuits are low temperature sensitive, the circuit descriptions are very simple. The circuit performances are depicted trough PSPICE simulations, they show go...

A mixed-signal circuit that can emulate multi-layer perceptron neural networks is presented. The sequential processing provides a tradeoff between speed, power consumption and circuit area, allowing a flexible accommodation of different network structures. The design of the three most critical analog basic blocks of the processor is presented. a) Dynamic analog memories: A technique of switchin...

BACKGROUND Volume targeted pressure support ventilation (VT-PSV) is a hybrid mode increasingly used to maintain a minimal tidal volume (VT) by automatically adjusting the level of inspiratory pressure. The objective of the study was to determine the ability of home ventilators to maintain the preset minimal VT during unintentional leaks in a VT-PSV mode. METHODS Seven ventilators were tested ...

The increased circuit density in today’s integrated circuits demands for efficient and low cost testing as compared to the testing of logic with external test equipment. The Built-In Self Test (BIST) architecture provides the self-testing of logic circuit but is not at the positive extreme in delivering deterministic and limited test vectors and storage and compression of output test responses....

Reducing the power consumed by the device is the emerging trend now-a-days. The aim is to reduce the leakage current of the circuit by using the Sub Clocking technology. It is the process of switching the circuit by means of partially ON to reduce the power consumption. There are two modes of operation are implemented. Half Mode Operation (HMO), Full Mode Operation (FMO). These modes of operati...

In this paper, a new voltage-mode first order allpass filter using minimum active and passive components is presented. The proposed circuit employs one fully differential second generation current conveyor (FDCCII), one grounded capacitor, one resistor and offers the following advantages: the use of only grounded capacitor which is attractive for integrated circuit implementation, low active an...

The paper deals with current conveyor based design criteria for low power Miller operational transconductance amplifier. Its transconductance has been controlled by using second generation current conveyor (CCII), replacing input bias current (Ibias). Current-mode based electronics devices becoming more popular than with voltage mode. The performance is obtained through PSPICE simulations which...

Application of a single phase rectifier as an example in teaching circuit modeling, normalization, operating modes of nonlinear circuits, and circuit analysis methods is proposed. The rectifier supplied from a voltage source by an inductive impedance is analyzed in the discontinuous as well as in the continuous conduction mode. Completely analytical solution for the continuous conduction mode i...
