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,
