Apr 20, 15, I still notice the output in the simulator is same. 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.

I read about input protection http: You might get better ccmos with a different arrangement of the RC components – http: 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.

A CD will not blow up unless you connect the power supply backwards. What is wrong in this circuit?

No, create an account now. Your simulation software is wrong because it shows the input going 4V higher than the positive supply and 4V below ground.

The datasheets of Cmos gates shows that they switch their output in only 50ns 0. Your simulation sofware is also wrong when it shows the very slow switching ramps 0.

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, The wave is not exactly square in shape. You get oscillator and counter in one.

Your Yenka sim software doesn’t know if it is coming or going. I have created the following image attached NAND gate oscillator using 2 gates.

The absolute max supply for a high speed 74HC is 7V and they recommed a max of 6V. NAND gate oscillator frequency calculation Posted by ukiceman in forum: Hi beenthere, I have made a new circuit. Hi Audioguru, I changed the circuit as per your suggestion. 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 got rid of the switch that shorts the output to ground, was using it as a reset.


Your name or email address: Is it good enough to run a binary counter? May 11, I don’t know why your oscillator has a switch at its output that shorts the output to ground. Dec 20, 10, 1, Your oscillator has both inputs of the gates shorted together.

Why do you use a very high value resistor 1M feeding the oscillator to the counter’s clock input?

The circuit supply voltage is 12v. Aug 6, 7. The diodes at the input protection of Cmos gates clamps the input voltage to 0. Aug 6, 9. Aug 5, 2. The resistor is not needed if the ICs use the same power supply voltage. Aug 6, 8. Discussion in ‘ General Electronics Chat ‘ started by smartyramAug 5, Aug 7,
