Hi, do you have an idea to convert voltage into frequency but using only OpAmps and some basic circuit elements like resistors, capacitors, inductors and diodes?
Or, how can i change the duty cycle of a square wave, with respect to the voltage. In other words, I want a converter like voltage to duty cycle.
I thought to do it like following;
I will take the integral of square wave, and obtain a triangular wave, using integrator circuit.
Then using a comparator circuit, I will reconstruct the square wave.
But, the problem is that, I want 0 duty cycle when I have a 0 voltage to compare, and increasing the voltage, I want to obtain greater duty cycles. But this method gives 50 duty cycle, at voltage 0.
Thank you
