Aug 6, Dec 20, 10, 1, You get oscillator and counter in one. The diodes at the input protection of Cmos cmoos clamps the input voltage to 0.
Aug 6, 9. Your SIM program nanf know that the input of Cmos gates have input protection diodes that limit the input voltage to plus and minus 0. Aug 5, 1. I don’t know why your oscillator has a switch at its output that shorts the output to ground. NAND gate oscillator frequency calculation Posted by ukiceman in forum: Hi Audioguru, I changed the circuit as per your suggestion.
Why do you use a very high value resistor 1M feeding the oscillator to the counter’s clock input? May 11, Quote of the day. If only one input is used and the spare input is connected to the positive supply voltage then the output will be more symmetrical.
Aug 6, 5. Your name or email address: The circuit supply voltage is 12v. Aug 7, Is it good enough to run a binary counter? Hi beenthere, I have made a new circuit. Aug 6, 6. 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 sense of touch.
What is wrong in this circuit? I read about input protection http: Your simulation sofware is also wrong when it shows the very slow switching ramps 0. The wave is not exactly square in shape. You May Also Like: Do cmo already have an account?

Aug 6, 7. The 1M resistor between the oscillator and counter is not required and might stop the circuit from working because it will combine with stray capacitance between wires and cause the square-wave from the oscillator to be a triangle-wave at the clock input of the counter.
Aug 5, 17 2. Your Yenka sim software doesn’t know if it is coming or going. Your oscillator has both inputs of the gates shorted together. Aug 6, 8. Your simulation software is wrong because it shows the input going 4V higher than the positive supply and 4V below ground. I have created the following image attached NAND gate oscillator using 2 gates. No, create an account now. The datasheets of Cmos gates shows that they switch their output in only 50ns 0.
I got rid of the switch that shorts the output to ground, was using it as a reset. You might get better results with a different arrangement of the RC components – http: The absolute max supply for a high speed 74HC is 7V and they recommed a max of 6V.
A CD will not blow up unless you connect the power supply backwards. Feb 17, 4, 1, Aug 5, 3.
Discussion in ‘ General Electronics Chat ‘ started by smartyramAug 5, Would appreciate any feedback from you? I still notice the output in the simulator is same.
