For the last few decades Complementary Metal-Oxide Semiconductor (CMOS) has replaced NMOS and PMOS for implementing high speed ICs for its less power consuming characteristics and has become industrial standard for implementing Very Large Scale Integrated (VLSI) circuits. In recent days CMOS technology is being scaled into nanometer level to achieve higher switching speed, higher complexity, smaller circuit size and smaller power consumption. CMOS technology imposes unavoidable limitations after scaling into nanometer level such as subthreshold leakage current, short channel effects, high fabrication costs and interconnect delay etc. and therefore, the outcome is not satisfactory. To solve this many alternative technologies has been proposed in last few years among which QCA has been proved to be most promising technology . A lot of digital circuits have been designed using QCA which includes encoder also. In this paper an alphanumeric symbol encoder circuit is designed using QCA technology. The QCA circuit has been simulated in QCADesigner tool.
