True Random Number Generator (TRNG) based on CMOS designed compact discrete-time chaotic oscillator is presented. The chaotic oscillator was designed using 3 transistors map circuit in order to construct an approximate V-shape characteristic (inverse tent map). Simulation of the chaotic oscillator was described and examined in terms of bifurcation diagram and transient waveform to show that it has...
A simple continuous-time chaotic oscillator is described. The oscillator is designed based on widely studied double-scroll chaotic behavior and thought the use of approximating hyperbolic tangent function as a nonlinear part. Gm-C integrators are primarily employed as the simplest component for performing the three-dimensional differential equations of jerk system. The chaotic dynamics are examined...
This paper presents chaotic oscillation-based built-in self-test (BIST) for CMOS operational amplifier. The proposed BIST technique is based on the use of designed operational amplifier (op-amp) in the unity gain buffer of discrete time chaotic oscillator as circuit under test (CUT) of BIST. The presented BIST detected faults by using a differentiation of chaotic output signal among fault free and...
This paper presents a low-power discrete-time chaotic oscillator based on approximately non-linear characteristic. The oscillator circuit consists of an inverter and subtractor operational amplifier (Op-Amp) in order to controlled transfer characteristics by gain of Op-Amp. The circuit has been using as a chaos map that generates discrete-time chaotic signal. Simulations of proposed circuit are described...
