Dec 20, 10, 1, Aug 5, 3. I still notice the output in the simulator is same. The resistor is not needed if the ICs use the same power supply voltage. The diodes at the input protection of Cmos gates clamps the input voltage to 0.

Hi Audioguru, I changed the circuit as per your suggestion. Your name or email address: I read about input protection http: The 1M resistor between the oscillator and counter fmos not required and might stop the circuit from working because it will combine with stray capacitance between mand and cause the square-wave from the oscillator to be a triangle-wave at the clock input of the counter.

Your simulation software is wrong because it shows the input going 4V higher than the positive supply and 4V below 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.

Hi beenthere, I have made a new circuit. Quote of the day. 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: The absolute max supply for a high speed 74HC is 7V and they recommed a max of 6V. The circuit supply voltage is 12v.

Your Yenka sim software doesn’t know if it is coming or going. You get oscillator and counter in one. Your simulation sofware is also wrong when it shows cmps very slow switching ramps 0.

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. Aug 6, Aug 5, 17 2. Aug 7, Why do you use a very high c4011 resistor 1M feeding the oscillator to the counter’s clock input? The datasheets of Cmos gates shows that they switch their output in only 50ns 0. I have created the following image attached NAND gate oscillator using 2 gates.

Yes, my password is: I got rid of the cmoz that shorts the output to ground, was using it as a reset. Maybe it will be simpler to use Aug 6, 5. Apr 20, 15, Feb 17, 4, 1, Aug 6, 6. Nanc 5, 1. You might get better results with a different arrangement of the RC components – http: Aug 6, 4.
