4-bit adder subtractor circuit. A 4-bit Full Adder is designed to generate a 4-bit Sum and is designed by combining four 2-bit Full Adders and as a result shows the Four bits output along with the ...

This project demonstrates building a 4-bit binary adder using individual transistors. Each component is built from the ground up, from basic logic gates to the complete adder circuit ...

The proposed circuit is based on carry-propagation schemes and can be partitioned to perform one 64-, two 32-, four 16-, and eight 8-bit additions. When the Austria Mikro System (AMS) 0.35 /spl mu/m 2 ...

We left Part 1 with a mission, which was to ponder how we might go about creating single digit BCD 8421 adder; that is, a logic function that can accept two BCD 8421 digits, along with a carry-in bit ...
