Hi guys, I want to produce a PWM wave with a frequency of 140 Hz and a duty cycle of 0.8%. But, the commercial Oscillators or Timers usually generate a PWM with tens of kHz. I know the schematic below can output the PWM. Is it possible to get the PWM I expected? Or do you have a better scheme? I need the power consumption as low as possible, around several micro watts of tens of micro watts. Thanks.
