The tradition of implementing analogue circuits by means of voltage amplifiers is almost as old as the concept of electronic circuit design. The integrated electronic circuit, however, is a relatively new concept. Furthermore, integrated electronic circuits have significantly different limitations and strengths to the conventional discrete electronic circuits have. Since the active devices in i...

A new circuit for realization of universal current-mode filter using current Follower Transconductance Amplifiers (CFTAs) is presented. The proposed circuit realizes current-mode low pass, high pass and band pass filter functions simultaneously with a single current source at the input. The band reject and all pass filters can also be obtained from the proposed circuit without any extra hardwar...

In order to solve the problem of fuel pollution, the diesel fuel for power generation of marine was abandoned and shore power supply have been proposed at the historic moment. The Shore Power Supply which needs transferring 380V/50Hz to 450V/60Hz is used on shipping who need this kind of power, so effectively curbs the emissions of pollution gas into the air, and achieves the purpose of improvi...

In this paper, a voltage-current mode controller is proposed to adjust both the input current and DC voltage of a boost-inverter in order to improve the performance of the photovoltaic (PV). The proposed system is based on fuzzy-making-decision predictive voltage-current controller (FPVCC). The simulation results show that in case of using the proposed FPVCC, the input current of a PV array is ...

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 CMOS current-mode companding multiplier/divider composed of three compact logarithm circuits and one compact exponential circuit is proposed. Approaches for constructing the logarithm circuits and the exponential circuit are based on second-order Taylor series approximations. By gathering the three logarithm results and passing through the exponential circuit, we can obtain the result of zp(x...
