P pc88 New Member Jul 25, 2008 #1 I am looking for an easy way to generate a square wave with the following characteristics: - 200mVPP - 50 KHz frequency - able to source 40mA (will be used with loads as low as 5 ohms) My current idea is to use a small transformer. Any other ideas?

P pc88 New Member Jul 25, 2008 #3 Are you talking about a simple voltage divider? Since my load is around 5 ohms, ideally the Thevenin equivalent resistance of the divider would be much less than that.
