In this work, we have implemented 1-bit Full Adder Circuit using Pass Transistor Logic. Pass Transistor Logic is used
for high-speed technology and is easy to build the basic gate structures. The developed circuit is an extension of pass transistor
logic Ex-or gate. The 1-bit Full Adder Circuit has been performed and obtained I-V characteristics and power for sum and carry
were calculated. The effect of scaling on the overall performance is also analysed through the performance evaluation of 1-bit
full adder circuit. Simulation results have been performed on LT Spice tool simulator at 1.8v single ended supply voltage and
simulations are carried out to indicate the functionality of the proposed full adder circuit compared with conventional design to
verify the effectiveness and it shows the circuit has low power dissipation at high speeds.
