Realization of a novel single-resistance-controlled oscillator, employing an active element and all grounded passive elements, is the purpose of this manuscript. With requirements for completing the design being only a single Voltage Differencing Current Conveyor and four grounded passive components, it is also a preferable choice for integrated circuit implementation. The designed circuit has ...

This paper presents a second order voltage mode quadrature sinusoidal oscillator using a recently reported active building block, namely the differential voltage current controlled conveyor transconductance amplifier. The circuit proposed here employs single differential voltage current controlled conveyor transconductance amplifier, two grounded resistors and two grounded capacitors. The use o...

Introduction: Oscillation based test (OBT) method [1] has been applied to testing different types of analogue circuits [2-5]. In this approach, the circuit is transformed into an oscillator during the test mode and the frequency of oscillation is measured and compared to the reference value obtained on a known-good circuit operating in the same conditions. Circuit modification for the purpose o...

A new quadrature oscillator circuit using a single differential voltage current conveyor transconductance amplifier (DVCCTA) and four all grounded passive elements is presented. The proposed circuit provides two current quadrature outputs at high impedance and three voltage quadrature outputs simultaneously. The oscillation condition and oscillation frequency are independently controllable. The...

In this paper, a method of low power analog testing is proposed. In spite of having Oscillation Based Built in Self-Test methodology (OBIST), a look up table based (LUT) low power testing approach has been proposed to find out the faulty circuit and also to sort out the particular fault location in the circuit. In this paper an operational amplifier, which is the basic building block in the ana...

Linear system theory provides an inadequate characterization of sustained oscillation in nature. In this two-part exposition of oscillation in piecewise-linear dynamical systems, we guide the reader from linear concepts and simple harmonic motion to nonlinear concepts and chaos. By means of three worked examples, we bridge the gap from the familiar parallel RLC network to exotic nonlinear dynam...

In a hybrid IGBT module with SiC diodes as free-wheeling diodes, high frequency oscillation occurs during turn-on due to the fast switching transient of SiC diode and the resonance between circuit parasitic inductances and the junction capacitance of SiC diode. Such oscillation causes EMI noise which may affect the performance of the system. Methods to mitigate the turn-on oscillation are studi...

This article presents a current-mode quadrature oscillator. The proposed oscillator can provide 2 sinusoidal output currents with 90 0 phase difference. It also provides high output impedances that make the circuit able to directly drive load without additional current buffer. The condition of oscillation and frequency of oscillation can be controlled independently and electronically by adjusti...
