An electrical engineering research team at National Cheng Kung University in Taiwan has developed three new circuit designs that consume 80 percent less energy than current technology. The new converter processes, dubbed monotonic capacitor switching procedure, binary-scaled error compensation method and binary-scaled error compensation method, allow for both high-efficiency and faster operating speeds.  The research was recently featured at the International Solid-State Circuits Conference.
