A Subthreshold - CMOS Chaotic

Synchronization of Subthreshold-cmos Chaotic Oscillators

This paper reports on the design and chip measurements from synchronous coupled chaotic oscillators operating in subthreshold CMOS. Each uncoupled oscillator is autonomous and generates chaotic signals with three state variables. For commensurate bandwidth, the subthreshold designs utilize currents and capacitors over 200 times smaller than above threshold realizations. The reduced size makes s...

A SUBTHRESHOLD-CMOS CHAOTIC OSCILLATOR - Circuits and Systems, 1996., ISCAS '96, 'Connecting the World'., 1996 IEEE International Symposium

This paper reports on the design of a subthreshold-CMOS chaotic oscillator based on Chua's circuit. The circuit is autonomous and generates chaotic signals from three state variables in a manner analogous to a Chua circuit. Previous CMOS IC versions of the Chua circuit operate above threshold and make use of capacitors over 200 times larger than the subthreshold design. Also, this design is bas...

A Chaotic Oscillator Cell in Subthreshold Cmos for Spatio-temporal Simulation

This paper reports on the design and experimental results of a subthreshold-CMOS chaotic oscillator suitable for single-chip VLSI synthesis of coupled maps generating spatio-temporal chaos. The circuit is autonomous and generates chaotic signals in three state variables in a manner analogous to a Chua circuit. Previous CMOS oscillators operate above threshold and utilize current over two orders...

A CMOS Unit Circuit Using Subthreshold Operation of MOSFETs for Chaotic Boltzmann Machines

Sub-threshold Logic for Ultra-Low Power Consumption

In the ultra low power end of design spectrum when performance is of secondary importance, digital subthreshold logic circuits are more applicable than the regular MOS logic. In this paper, we propose two different subthreshold logic families: 1) variable threshold voltage subthreshold CMOS (VT-Sub-CMOS) and 2) subthreshold dynamic threshold voltage MOS (SubDTMOS) logic. Both these logic famili...
