Dual-Output Second-Generation Current Conveyor-based Voltage-Mode Sinusoidal Oscillator modified for Chaos Generators
نویسنده
چکیده
Two chaos generator circuits using dual-output second-generation current conveyors [DO-CCIIs] as active devices with grounded passive components are realized. The starting circuit is a voltage-mode four-phase sinusoidal quadrature oscillator [VMFPSQO] circuit for realizing both the chaos generators. The first chaos generator is derived by modifying the VMPFSQO by inserting an additional frequency dependent negative resistor [FDNR]. This is to introduce the non-linearity into the sinusoidal oscillator. In the second chaos generator, non-linearity in the sinusoidal oscillator is introduced by using an additional block consists of an FDNR followed by a differentiator. The use of all grounded passive components makes both the generator circuits most suitable for monolithic implementation in contemporary IC technologies. The chaos generators are designed and verified using PSPICE simulation with good results.
