CMOS N-Dimensional M-Level Hysteresis Circuits and Possible Applications

Hysteresis is a natural phenomenon existing in many systems. Binary hysteresis is the simplest yet important model to study electronically generated hysteresis. Binary hysteresis circuits, the Schmitt trigger being an example, are widely used in reducing noise sensitivity, designing oscillators, generating chaotic signals, etc. A new concept, n-dimensional m-level multi-cell hysteresis is presented. A group of CMOS binary hysteresis circuits with full control which operate in all four quadrants is introduced. CMOS circuits, that give various one-dimensional multi-level hysteresis, in both current mode and voltage mode, are presented. Various combinations of adding forward…
