AbstractSubstantial increase of output current, and Ion / Ioff ratio for sub-7nm low power CMOS transistors, can be accomplished using a novel optoelectronic technology, which is 100% compatible with existing CMOS process flow. For RF or mixed signal ASICs, adding photonic components may improve the cut-off frequency, and reduce series resistance. Products that utilize power regulating devices, such as power MOSFETs, will benefit from the optoelectronic configuration to achieve much lower Rdson and high voltage at the same time. For semiconductor memories, such as DRAM or FLASH, the photonic technique may reduce the ERASE / WRITE / access time and improve the reliability.

The high-voltage general inverter which has the advantage of the structure， has become the key equipment to saving energy in recent years. The inverter output current is the key variable of overload protection, over current protection and V/F control compensation, so the real-time accurate measurement of its RMS is extremely important. In this paper, the output current signals preprocess by hardware filter firstly, and then find the RMS of the current signal in the period of the waveform. Meanwhile, this algorithm belong to true RMS algorithm category, which suitable for testing harmonic current signal, and can avoid mean filter to reduce the computation time. By using this algorithm, the inverter control system provides accurate reference for overload protection reduces the systematic disoperation rate and sets the more accurate security allowance to ensure the safe operation of equipment.
