| Triangular wave on ring oscilator |
| (1/3) > >> |
| Belrmar:
I recently got my first analog oscilloscope, so to start checking its integrity i built a ring oscillator, to my surprise the output from 2 of the 3 Schmitt trigger inverters are , instead of square waves , triangular, i am using only capacitors so might it be that the trigger output is getting loaded?but i am using the same capacitors so i dont know why i would have 1 of the triggers giving a propper square wave any ideas ? |
| Lee Leduc:
Please post a schematic. People can't help without seeing your circuit. Thanks |
| Belrmar:
on each of the outputs there is a capacitor to slow the process down |
| Brumby:
How do you think the capacitors slow the process down? Just look at one point and think about the voltage across one of the capacitors.... |
| Belrmar:
well the output circuitry of each inverter will have to charge up the capacitor before it triggers the next inverter input into going low... i guess, also without them the circuit is not precisely stable, it just outputs a bunch of noise or something too high freq for my oscilloscope |
