well, I have a similar circuit and I have a problem...

I need to built a F-V converter but the output voltage needs to be linear (100 Hz = 100 mV, 1 kHz = 1V and 10 kHz = 10V). I started my circuit with a comparator to convert my sine wave into a squared one, after that I conected it to a Pulse forming circuit with a threshold of 0.08V ( you can see my circuit made in Pspice attached) everything works great @ 10kHz I got 5.3 V, @ 5kHz i got 2.4v ans so on, but @ 100 Hz it doesn't work.. I hope anyone can Help me.......

Thanks
