A versatile precision rectifier based on a current conveyor and current mirrors is presented. The proposed circuit performs positive half-wave, negative half-wave, positive full-wave, and negative full-wave rectification into a single circuit. The current-mode technique has been employed to provide the high-precision capability of the circuit. The circuit configuration is very suitable for inte...

Conventional asynchronous control circuit design is complex because potential designs must be analysed for the existence of hazards and state variable races, as these may cause incorrect circuit operation. We present the innovative CMOS direct-mapped asynchronous circuit design approach, which, by defining a one-to-one mapping between state diagram and CMOS circuit implementation, removes the n...

The control of SRM was discussed: current chopping control, angle position control. This paper presents an inverter circuit and a fuzzy sliding mode control method to minimize the torque fluctuation and noise of the SRM. Based on the experimental results, Using the inverter circuit and fuzzy sliding mode control method can effectively minimize the torque fluctuation and noise of the SRM, For th...

Abstract: We proposed a concept of balanced switching converter circuit, which is an effective way to reduce the common-mode conducted noise by current cancellation. In this paper, the path of the noise current in a balanced boost converter circuit is investigated using a current probe. By measuring current waveforms and frequency spectra of the parasitic capacitances and the frame ground line,...

A power management controller circuit with a switched-capacitor mode down-regulator and a battery charger block for semi-active radio-frequency identification (RFID) tags was proposed and fabricated. The major achievement of the proposed switched-capacitor mode downregulator and battery charger block is providing a low standby current internal voltage supply circuit and self-controlled thin fil...

This article describes the ways to preserve resonant mode in biparametric circuits with distributed parameters and studies effect of changes circuit power supply on mode. During moving part’s movement sensor due influence magnetic resistance steel part circuit, law change electrical inductance (distribution flux long conductors) differs from linear one.

New first order allpass filter (APF) in current mode, constructed from 2 CCCCTAs and grounded capacitor, is presented. The current gain and phase shift can be electronically /orthogonally controlled. Low input and high output impedances are achieved which make the circuit to be easily cascaded to the current-mode circuit without additional current buffers. The operation of the proposed filter h...

In the present work, a four-port model for inter-digital transducer was developed. This model was modified from Mason’s equivalent circuit and was ideal for the simulation of balanced mode surface acoustic wave devices. Inheriting the virtues of Mason’s model, this model included the energy storage effect and was capable to fit arbitrary polarity configuration of transducers. Simulation results...

This paper assesses the impact of Layered SpaceTime Multiuser Detection (LAST-MUD) in wireless circuit switched and packet switched modes integrated CDMA systems. The network is hence composed of packet and circuit radio mobile stations transmitting to an antenna array at the base station receiver. These users are organized in different groups and users in a particular group are allocated the s...
