I need the circuit for a 4 bit binary adder using JK Flip Flops.

 

Please read, then have another go.

Hi,

That's a fun assignment. It's a bit like having to make a car out of bricks - possible, but a bit clunky.

 

I need the circuit for a 4 bit binary adder using JK Flip Flops.

Adders don't require flip-flops. It's a combinatorial circuit.

 

But think of the challenge.

 

Nonsense! Who would even think of such a question?

 

Some instructor in Bhopal, obviously.

......or not since the OP didn't say he was in school. The chief engineer might be engaged in a bit of hazing.

 

I am in an engg college. Could u atleast get me started in the right direction (regarding the assignment), however silly it might seem to u at present.

I already did. A binary adder is a combinatorial circuit which can be synthesized with logic gates alone. The input values and output values may be held in registers constructed with any of several different kinds of flip-flops. One of those types is the JK type.

The adder has three inputs, called operand A, operand B, and Carry In. It produces two outputs called Result and Carry Out. The carry out from one stage is connected to the carry in of the next stage. The carry in to the lowest stage can be set to zero. Make yourself a truth table and just do it! Is that enough help or do you still need more?

 

Thanx!!

 

Thanx!!

It would be great if you could post your results for all to see.
