Hi there I have been working the following circuit:
Built in LTSpiceIV.
I am trying to input a square waveform, integrating this to become a triangular waveform, then through a summing amplifier to be able to vary the offset with a dc bias, then this triangular waveform is compared to a reference voltage which sets the output duty cycle of the square wave produced.
My problem is that my first voltage divider circuit does not provide the voltage I require, could anyone help with this ?
