2 Bit Magnitude Comparator Using Logic Gates. Schematic of proposed 2 bit magnitude comparator using hybrid logic style it requires less number of transistors than other logic style. A 2 bit digital comparator will compare a1 a0 bits of input a with b1 b0 bits of input b resp.
Comparison is most basic arithmetic operation that determines if one number is greater than equal to or less than the other number. A magnitude digital comparator is a combinational circuit that compares two digital or binary numbers in order to find out whether one binary number is equal less than or greater than the other binary number. This comparator compares the two bits and produces one of the 3 outputs as l a b e a b and g a b.
A comparator used to compare two binary numbers each of two bits is called a 2 bit magnitude comparator.
Comparison is most basic arithmetic operation that determines if one number is greater than equal to or less than the other number. If input a 0 logic low then both gates are at zero potential pmos is on provide low impedance path from v dd. A magnitude digital comparator is a combinational circuit that compares two digital or binary numbers in order to find out whether one binary number is equal less than or greater than the other binary number. The circuit for a 4 bit comparator will get slightly more complex.
