Voltage-controlled Resistor Device Based on Phase Transition Materials

IntroductionCircuit designers often require a resistor that consistently alters its resistance based upon an input control voltage. A voltage-controlled resistor (VCR) is a three-terminal device that varies the resistance between two terminals relative to voltage in the third terminal. VCRs are commonly used in the following electronics: variable gain...
