– In recent years it has been observed that some power converters can exhibit deterministic chaos. Since converters have wide industrial applications, it is useful to study their bifurcation phenomena in order to understand the change of behaviors as circuit parameters are varied. Therefore this paper aims to investigate some complex dynamic phenomena that can occur in currentprogrammed DC-DC b...

This article presents a voltage-mode universal biquadratic filter performing simultaneous 3 standard functions: lowpass, high-pass and band-pass functions, employing differential different current conveyor (DDCC) and current controlled current conveyor (CCCII) as active element. The features of the circuit are that: the quality factor and pole frequency can be tuned independently via the input ...

A novel square wave generator (relaxation oscillator) with controllable frequency is described. It employs two universal current conveyors (UCC) and grounded passive elements. The generator includes integrator with two integration capacitors that alternate in charging which results in linear and precise control of frequency by voltage. New implementation of UCC with attractive properties in CMO...

This paper proposes a new resonant gate driver circuit for a soft switching synchronous buck converter in a fixed load condition. The switching energy can be fully recovered during current commutation phase in the gate driver while the diode conduction losses in the low and high side switches can be substantially reduced by employing additional L and C resonant in the circuit. Using PSpice simu...

The use of PSpice models for piezoelectric devices and ultrasonic transmission media is of major importance when designing electronics for ultrasonic systems.
