i need a design of a 50% duty cycle corrector...my idea is to multiply the frequency using frequency doublerx2 circuit and then divide it by 2 .......will this idea work? can someone give me the design of frequency multiplier circuit deisgn and the divider circuit design? need it urgently.....
There are severasl ways to get a double frequency:
You can use a designed CI but they are for GHz frequencies.
There are several ways to implement them: use an analog multiplier and in both input put the signal you want to double the frequency, at output yo need a band pass filter with center fequency at double of the frequency of the signal.
You can use also a PLL in fdrequency sinthesis with a frequency divider by 2. The output at the VCO is the double of frequency you ar looking up to.
1. You can use a designed CI but they are for GHz frequencies.

1. what is CI ? can you gave an example? or may be a circuit diagram ?
2. this method is what i am thinking to use...but what kind of the analog multiplier and band pass filter to be used? ( can give a circuit diagram?)
3. component for this PLL i cant find the component in Orcad pspice...is this an IC? how to operate it with the divider?(divider= a D flip-flop?)
actually what kind of simulator is good to simulate analog circuit? pspice, Hspice, cadence,mentor.....?
