In this paper, a level-shifting voltage-copier circuitry is introduced to convert one or two input voltage levels to eight voltage levels. The voltage copier consists of five kinds of conversion circuits. Each circuit includes only six to seven electronic components, which can ensure the simplicity and reliability of the voltage copier. A resonant inductor is further added to improve the performance of these circuits. A high-efficiency resonant voltage copier is introduced. Simulation and experimental results verify the performance of the voltage copier and the design method. The circuit family provides a useful method for voltage conversion under multiple-input sources to multiple outputs.
