Parallel Balanced-Bit-Serial Design Technique for Ultra-Low-Voltage Circuits With Energy Saving and Area Efficiency Enhancement.

Ultra-low-voltage (ULV) satisfies the energy-constraint on-die acceleration of parallel processing in battery-powered Internet-of-Things applications. However, ULV brings serious leakage energy, throughput reduction, and delay variation issues. Parallel bit-serialization remarkably reduces leakage energy and enhances area efficiency; however, extremely reduced critical path aggravates delay variat...
