Higher Dimensional

In order to operate in higher dimensional form of autonomous and nonautonomous Chua's circuits keeping their original chaotic behaviors, we have experimentally modified VOA (Voltage Mode Operational Amplifier)-based autonomous Chua's circuit and nonautonomous MLC [Murali–Lakshmanan–Chua] circuit by using a simple experimental method. After introducing this experimental method, we will present PSpice simulation and experimental results of modified high dimensional autonomous and nonautonomous Chua's circuits.

Component Matching

A new voltage-mode biquad with four inputs and four outputs using only two differential difference current conveyors (DDCCs), two grounded capacitors, and two resistors is proposed. The proposed circuit can act as a multifunction voltage-mode filter with one or three inputs and four outputs and can perform simultaneous realization of voltage-mode notch, highpass, bandpass, and lowpass filter signals from the four output terminals, respectively, without any component choice conditions. On the other hand, it also can act as a universal voltage-mode filter with four inputs and a single output and can realize five generic voltage-mode filter signals from the same configuration without any component-matching conditions. Finally, to verify our architecture, we have designed this analog filter chip with TSMC 0.35 μm 2P4M CMOS technology. This chip operates to 1.125 MHz and consumes 30.95 mW. The chip area of the analog filter is about 0.822 mm2.
