- Design and demo of an RC oscillator based on a CD4093 quad Schmitt trigger NAND gate. Includes schematic and scope shots.
Network XIII: Electronics projects, demos, builds and teardowns for hobbyists and makers. All are welcome.
Best explanation of Schmitt Trigger Oscillators on UA-cam. Great! Keep going!
Thank you !
This explanation is brilliant, a shame so few people have seen this
bjorn van der lande Thank you for your kind comment, it is much appreciated.
Just what I was looking for, thanks!
nice!!!!!!!!
thank u so much
This video is underrated.
Nice video - thanks!
Great!!!
Thank you!
The output square wave mark and space doesn't look like same. I'm thinking to get similar chip 74LS132 to make a Scope CRT TV and 2 gate for Sawtooth oscillator for Vertical and horizontal . 2 gate for self oscillate for Inverter for step up to few hudred voltage for CRT , LM1881 for Sync seperator.
Sir, I want 38 Khz frequency oscillator...with 4.42 volts as input voltage..what are the R and C values to be used..and what is the vp and vn values sir..please help me 🥺need it for college project sir
The design equation for a CD4093 based astable multivibrator is in the video, and also in the TI datasheet, which is where I found it: www.ti.com/lit/ds/symlink/cd4093b-q1.pdf
please send the datasheet reference link of Schmitt NAND gate where I used SN74LS132 series.

Network XIII thank you
Can you still get an oscillator with a regular NAND gate with no Schmitt trigger inputs?
Probably, though it wouldn't be as stable or predictable as this circuit.
starting to 3 minutes your are talking about charging capacity. But there is no input tension Vin connected anywhere in the circuit. HOW CAN YOU charge this capicitance ,?
kembo capelsii The capacitor is charged and discharged through R by the output of the first gate.
Thank you Very much for your fast answer. i see, but why the capacitor will discharge by the out 3 when it low, instead of to discharge by the ground. sorry I'm bigger i really want to understand everything ^^
Sorry for my late reply. The discharge path for C is through R, then into the output pin which is pulled low to ground, and back to the other side of C.
@@NetworkXIII the output when it at low level it's connect to ground right?
The lower output FET pulls the pin down to ground.
Brightness of paper irritating me.
