This 2-bit adder was a lot of work to build. It uses a total of thirty-six 555 timers and it does have the option of adding or subtracting numbers. It’s a rather unorthodox use of the part, d… ...

2-bit binary adder made using 2 half adders. INTRODUCTION A binary Adder is a digital circuit that performs arithmetic sum of two binary numbers provide with any length. A binary Adder is constructed ...

Fig. 8 shows the testbench circuit created for the simulation of 1-bit full adder. The VDD pin is connected to a DC voltage of 0.9V taken from analog library. The input pins A, B and C are connected ...

We report carry and sum circuits for a 2-bit adder. The 2-bit adders are designed to be part of a pipelined 2N-bit adder-accumulator. The ICs clock at a maximum of 19 GHz and were fabricated in InAlAs ...

Recent progress in silicon photonics1,2,3,4,5,6,7,8 has dramatically advanced the possible realization of heterogeneous logic circuits9,10. A variety of Boolean optoelectronic circuits have been ...
