Use Transistor As Variable Resistor at Anna Waugh blog

Use Transistor As Variable Resistor. I am aware that the npn is operating in the active region as a variable resistor where full resistance of 470k between c and b puts about. Main things are the minimum resistance you need and the \$. Sadly, it is difficult to use a bipolar transistor as a resistor. You can use a jfet or a lamp + ldr (light dependent resistor) to vary resistance, or as ignacio says, use an mdac to simulate a. The resistance is between the. A mosfet can easily be used as a variable resistor. If it was easy and generally applicable, they would. I would like to know it if is posible to use nmos transistor to act as a resistor with a sinusoidal power supply ? The field effect transistor as a voltage controlled resistor. You have to consider few important parameters before using as a variable resistor. The circuit i have is very simple; It can be done, but there are many limitations and special requirements.
