(SET) circuits for Brownian Motion Based Logic and Arithmetic Computation were investigated. Random fluctuations and noise are major factors interfering with the operation of nanometer scale elec-tronic devices and circuits, as the feature size decreases. In SET technology, one of these interfering effects, namely quantum tunnel-ing, is actually utilized for computations by controlling the transport of individual electrons. However, at the single electron level, random fluctuations are largely unavoidable. In previous research, Brownian Motion based building blocks were proposed which take advantage of random fluctuations to function.i.e, Conservative Join (CJoin)and Hub. However, the SET design of the CJoin had two major limita-tions when taking industrial implementation into account. Firstly, it had long diagonal wires that appear on the design literally. Secondly, the circuit parameters of the tunnel junction capacitances fell short of the industrial standard. In this research we present a new design
