# How can I realize this nonlinear resistor?

I want to know if it's possible to realize a circuit described by the equation

$$I = \sin(w V)$$

where $$\I\$$ is the current, $$\V\$$ the potential and $$\w\$$ a variable which characterizes the single circuit.

• It is possible, but it's a little involved. What you're looking for is a sine converter, generally made out of a multiplying DAC or analog multiplier, then a simple amplifier to convert that output voltage to a current. I suggest you read up on them, as there are limits to how well they can represent the sine transform. – Reroute Aug 26 at 8:11
• V is what potential? Do some sketch, use circuit editor to draw a basic schematics. w has units rad/V ? Since sin(x) gives no units, you missed something else. – Marko Buršič Aug 26 at 8:46
• I'm not sure if I'm right but isn't that just a voltage controlled oscillator with zero f0? – Prateek Dhanuka Aug 26 at 13:03
• What should your circuit do with sin(a) and sin(a + 360 °)? Is it possible to restrict a to the interval -90 to +90 °? – Uwe Aug 26 at 15:30
