A Beginner’s Guide To The Cmos
Your simulation software is wrong because it shows the input going 4V higher than the positive supply and 4V below cx4011. You might get better results with a different arrangement of the RC components – http: Your Yenka sim software doesn’t know if it is coming or going.
Your name or email address: Aug 5, 1. Yes, my password is: Your oscillator has both cos of the gates shorted together. I got rid of the switch that shorts the output to ground, was using it as a reset. Aug 7, Is it good enough to run a binary counter? I have created the following image attached NAND gate oscillator using 2 gates. The absolute nandd supply for a high speed 74HC is 7V and they recommed a max of 6V.
The wave is not exactly square in shape. You May Also Like: You get oscillator and counter in one. Apr 20, 15, Hi beenthere, I have made a new circuit.
Hi Audioguru, I changed the circuit as per your suggestion. If only one input is used and the spare input is connected to the positive supply voltage then the output will be more symmetrical. Dec 20, 10, 1, Do you already have an account? Aug 5, 3.

Would appreciate any feedback from you? Aug 6, 4. The diodes at the input protection of Cmos gates clamps the input voltage to 0. Quote of the day.
Your simulation sofware is also wrong when it shows the very slow switching ramps 0. The resistor is not needed if the ICs use the same power supply voltage. I don’t know why your oscillator has a switch at its output that shorts the output to ground.
4011 Quad 2-in NAND Gate CMOS IC
No, create an account now. Solar-Powered Graphene Skin Reproduces Sense of Touch Researchers at the University of Glasgow have created a solar-powered graphene skin that can simulate the cd0411 of touch. What is wrong in this circuit? Aug 6, 8.
I still notice the output in the simulator is same. Your SIM program doesn’t know that the input of Cmos gates have input protection diodes that limit the input voltage to plus and minus 0. I read about input protection http: The circuit supply voltage is 12v.
Aug 6, 5. Aug 6, 6. Aug 5, 17 2. Why do you use a very high cmmos resistor 1M feeding the oscillator to the counter’s clock input?
