Hi, I want to set something up so that I can charge, and then immediately discharge a capacitor. With a relay, this would be simple, but I want to use transistors so I can do it at higher frequencies.
I have a couple of pulse generators (PWM-OCX) that can be linked together so that when one is on, the other is off, and visa-versa. I was thinking that I could set these up so that one charges the capacitor, then the other discharges it. The problem is that these circuit have an "open collector output". This means that the collector (source in this case as they are mosfets) is always grounded.
Is there some way I could modify these or add an extra transistor/diodes to do this?
