摘　　要：This paper presents an 8-bit sub-threshold microprocessor which can be powered by an integrated photosensitive diode.With a custom designed sub-threshold standard cell library and 1 kbit sub-threshold SRAM design, the leakage power of 58 nW,dynamic power of 385 nW @ 165 kHz,EDP 13 pJ/inst and the operating voltage of 350 mV are achieved.Under a light of about 150 kLux,the microprocessor can run at a rate of up to 500 kHz.The microprocessor can be used for wireless-sensor-network nodesThis paper presents an 8-bit sub-threshold microprocessor which can be powered by an integrated photosensitive diode.With a custom designed sub-threshold standard cell library and 1 kbit sub-threshold SRAM design, the leakage power of 58 nW,dynamic power of 385 nW @ 165 kHz,EDP 13 pJ/inst and the operating voltage of 350 mV are achieved.Under a light of about 150 kLux,the microprocessor can run at a rate of up to 500 kHz.The microprocessor can be used for wireless-sensor-network nodes
