"한국 반도체산업의 경쟁력"

IDEC에서 설계인력양성의 발판을 마련하겠습니다.

IP명 A Self-Powered Wireless Gas Sensor Node Based on Photovoltaic Energy Harvesting
Category Mixed Application Energy Harvesting
실설계면적 5㎛ X 5㎛ 공급 전압 1.2V
IP유형 Soft IP 동작속도 10kHz
검증단계 Simulation 참여공정 HM-2003
IP개요 A self-powered gas sensor integrated circuit (IC) suitable for wireless sensor nodes is designed in 0.18μm CMOS process. A dual-input shared-inductor boost converter is used to harvest energy efficiently from two PV cells instead of connecting these cells in parallel when the system is exposed to gases. This shows 11% improvement of conversion efficiency at 2% H2 gas concentration. Maximum end-to-end efficiency of 88% is achieved at a maximum available power of 446.6μW from two PV cells, and the quiescent current is only 270nA.
