guys i am working on a project design cmos digital comparator using manchester carry chain..i am working on this conference paper :New Efficient Design of Digital Comparator-WANG Guangjie, SHENG Shimin, JI Lijiu
Institute of Microelectronics, Peking University. at the back of the paper there is the schematic of manchester comparator..but it is very blur..can anyone help me with the design by giving some idea..pls

 

There are over 100,000 hits on "manchester carry chain" - http://en.wikipedia.org/wiki/Carry_look-ahead_adder

You can always get the data sheet for a 7485 to see the internal logic for a digital comparator.

 

hey thanks for the reply..basically i need to design a digital comparator based Manchester carry chain using Dsch software ..it not a hardware project...the design is at the back of the conference paper..i tried to reversed engineer it..but when i simulate its not working...can u help me..

 

Maybe the guy who wrote the paper can't get it to work either. Wouldn't be the first time a fraud was perpetrated. Sounds like a dubious claim.
