Would appreciate any feedback from you? The circuit supply voltage is 12v.

The diodes at the input protection of Cmos gates clamps the input voltage to 0. I read about input protection c,os Aug 5, 17 2. Your simulation software is wrong because it shows the input going 4V higher than the positive supply and 4V below ground. NAND gate oscillator frequency calculation Posted by ukiceman in forum: Is it good enough to run a binary counter?

Your simulation sofware is also wrong when it shows the very slow switching ramps 0. I got rid of the switch that shorts the output to ground, was using it as a reset. Maybe it will be simpler to use Why do you use a very high value resistor 1M feeding the oscillator to the counter’s clock input?

Hi beenthere, I have made a new circuit. The datasheets of Cmos gates shows that they switch their output in only ccmos 0. You May Also Like: The resistor is not needed if the ICs use the same power supply voltage.

Your oscillator has both inputs of the gates shorted together.

Yes, my password is: A CD will not blow up unless you connect the power supply backwards. Quote of the day. Aug 6, 7.

Aug 6, 9. Aug 7, The absolute max supply for a high speed 74HC is 7V and they recommed a max of 6V. May 11, 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 cd4011 the square-wave from the oscillator to be a triangle-wave at the clock input of the counter.

If only one input is used and the spare input is connected to the positive supply band then the output will be more symmetrical. Aug 6, 4.

I still notice the output in the simulator is same. Discussion in ‘ General Electronics Chat ‘ started by smartyramAug 5, The wave is not exactly square in shape.

I have created the following image attached NAND gate oscillator using 2 gates. Aug 6, 6.

Do you already have an account? I don’t know why your oscillator has a switch at its output that shorts the output to ground.

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. Aug 5, 3. Aug 5, 1. What is wrong in this circuit?
