There is no obvious reason why I do not use an oscillator. Its just that I cannot figure out why the 74HC04 ring oscillator configuration does not work.
Hi,
I am trying to build a 32MHz clock signal from a ring oscillator circuit. I used 74HC04 CMOS inverters [five of them] but the maximum frequency i could get was only 20Mhz. I reduced the number of inverters to 3, but i could get only 23MHz. I found the 74HC04 was rated to operate for...
