.MICROPOWER C-MOS
OSCILLATOR, DRAWS ONLY 0.5uA
If truly low power oscillators interest you, this circuit draws a mere 2 microwatts (500nA) from a 6v battery. It uses a very inexpensive C-MOS IC
to produce a frequency of 2Hz. However, by changing the component values you can push it to 300Hz. The circuit draws much less current than
traditional C-MOS oscillators using a Schmitt trigger inverter. It also produces fast leading edges. However, if you need more drive current, a
C-MOS buffer should be included. Published in EDN, September 2, 1993. |
