Abstract: A logic circuit comprising a quaternary logic switching circuit which includes a multilevel storage cell (MLSC), and the trinary or variable threshold logic means to yield an improved space, power, and time-efficient performance device is disclosed. The present invention is used for the implementation of a customized new logic design to further improve the cost-effectiveness of the application. Advanced circuit solutions are provided using asynchronous clock controlled functional units which are field programmable. A diode capacitor ladder chain is also used on an on-chip power supply multiplier to support internal high voltage operations. A digital-to-analog-to-digital translation (DADT) apparatus is also provided utilizing the above identified circuits. Finally, a printed circuit board (PCB) net driver with a trinary signal wire provides 50% bandwidth increase over conventional binary solutions.
