Simple oscillator circuit
2001-07-09 by Dharma Bummer
Does anybody know where to find a simple sine or square wave oscillator that runs off a negative power supply (-15 VDC, to be exact) and hence produces a negative wave (i.e., power fluctuating between 0 and -15 VDC)? I have a good square wave schematic utilizing a 741 op-amp, but I can't figure out for the life of me how to make it run off negative voltage and produce the negative square wave that I need for the project I'm working on...
