Generating -5VDC from +5VDC

Generating -5VDC from +5VDC
If you happen to have the March 1984 issue of Radio-Electronics, turn to page 78. This issue has the very first instalment of Robert Grossblatt's Designer's Notebook column. In it, he shows a simple circuit which will supply a negative voltage, given a positive voltage. It's basically a 555-based oscillator, and a voltage-doubling rectifier. He claims the negative-voltage output should be good for about 60ma. No-load voltage should be pretty close to the input voltage (but negative), although the voltage will drop a bit, depending on the load. If you put +5V into the circuit, it'll give you around -5V out. load. If you put +5V into the circuit, it'll give you around -5V out. If the load makes the voltage drop too low (-3V or -4V), you could always just feed the circuit with a higher voltage (like maybe 9V or 12V) and then just regulate the output down to -5V using a 7905 regulator. I've used this circuit a couple of times for powering op-amp's, and it works great! I'm not that great at ASCII-art, but I'll give it a shot. If the following schematic doesn't make sense, let me know, and I'll try it again...Note: In the above diagram , both diodes point down (the anodes are at the top). Also, watch the polarity of C1 & C3. The circuit is set up to oscillate at about 45kHz, with a duty cycle pretty close to 50%. None of the values of any of the parts are terribly critical, so if the capacitors or resistors are in the ballpark , it should still work okay.   (View)

smitt-trigger
This is a smitt-trigger (a circuit with hysterysis) which alternating charges and discharges a capacitor through a resistor. If the output voltage is low the upper led is lighted the current throug the led is limmited by the series resistor. If the output is high the lower led is lighted.   (View)

Ultrasonic transducer oscillator circuit
Allows the transducer to oscillate at its self-resonating point, with no tedious setup. As far as I can tell, the circuit will run on 5V-9V.   (View)
