Help me design a frequency multiplier

[shanmei]

hi,

how to design a frequency multiplier, I donot refer to pll, but a simple circuit like frequency divier which is made by DFF. Anyone has ideas?

Thanks

Hi,

i don't get u r Question completely!!
anyway if u r looking for simple multiplier, like simple divider using DFF

U can use Class C amplifier, with tank tuned to multiples of your input.

Hope this helps. If u find any other way let me know!!

Thanks,

With your input frequency you could synchronize an oscillator tuned to the required output frequency.

If your input frequency is a triangle or square wave, it owns harmonics. With a bandpass, select the required frequency (it will be a sinus), and amplify (& limit) it, if necessary.

frequency multiplier for a square wave

I think what you mean is a Delay Locked Loop Right. Search for it on google.

AFAIK a DLL has nothing in common with a frequency multiplier!

DLLs are used to double clocks in CPLDs

Can u please explain. What is TLP ?

simple multiplier frequency

Translinear principle. Non-linear arithmetic operations are achieved with ease with TLP circuits. Second chapter in Toumozou's book on Current mode circuits is the material to start with which is written by Gilbert, the inventor of these class of circuits.
