Chaos signal generator circuit using voltage-controlled variable resistor

摘要

PURPOSE: A continuous time type chaos signal generation circuit using a voltage control variable resistance is provided to indicate the state variable of a chaos equation by controlling a consequent operational point indicating a current-voltage curve characteristic of a non-linear negative-resistance. CONSTITUTION: A variable resistor(R) serially connects to the one side of an inductor-first capacitor circuit in a cutting node. A non-linear resistor is connected to the space between the other side of the variable resistor and the other side of the inductor-first capacitor circuit. A second capacitor(C2) is connected to the non-linear resistor in parallel. The variable resistor is implemented as a MOS transistor. The variable resistor includes a control transistor connected to the both ends of the variable resistor source and drain terminals.
