CMOS Design of Chaotic Systems Using Biquadratic OTA-C Filters

Journal of Low Power Electronics and Applications
This manuscript shows the CMOS design of Lorenz systems using operational transconductance amplifiers (OTAs). Two Lorenz systems are then synchronized in a master–slave topology and used to implement a CMOS secure communication system.

Birational maps that send biquadratic curves to biquadratic curves

, 2015
Recently, many papers have begun to consider so-called non-Quispel-Roberts-Thompson (QRT) birational maps of the plane. Compared to the QRT family of maps which preserve each biquadratic curve in a fibration of the plane, non-QRT maps send a biquadratic ...

Low-Power and Widely-Tunable Linearized Biquadratic Low-Pass Transconductor-C Filter [PDF]

A sixth-order low-pass $g_m$-C filter with a very wide tuning range ($f_c$ = 100 Hz to 10 MHz) is presented. The wide tuning range has been achieved without using switchable components or programmable building blocks.
