Question on Digital design

[Shanthanayaki]

Hi everyone,

What kind of combinational logic can be used to double the output frequency.
I tried the one form this website, https://www.hitequest.com/Hardware/a6.htm

but it doesn\'t work for me. Can anyone help ?.

Thanks,
Shantha

Hi shantha,

Have u taken care that sum of the delays of the two inverter should be 1/4 the time period of the clk ur applying at the input of combi circuit.

The combi ckt as it looks should work.
I wanted to know what is the output ur getting?

Regards
Mahanthesh
