摘要

绿色能源的能量提取电路技术和功耗为1mw级的超低功耗SOI电路技术为移动设备提供了自供电运行。可变级开关电容型DC-DC变换器方案使为绿色能源的lsi提供恒定电压成为可能。介绍了采用0.35-/spl mu/m FD-SOI工艺制作的1-V 300mhz频段压控SAW振荡器电路和0.5 v CPU。我们验证了这些电路在自供电无线移动系统中的有效性。

SOI circuit technology for batteryless mobile system with green energy sources

Energy-extracted circuit technology for green energy sources and ultralow-power SOI circuit technology with 1 mW level power dissipation provide self-powered operation of mobile equipment. A variable-stage switched-capacitor-type DC-DC converter scheme makes it possible to supply a constant voltage to LSIs for green energy sources. A 1-V 300 MHz-band voltage-controlled SAW oscillator circuit and a 0.5-V CPU fabricated with 0.35-/spl mu/m FD-SOI process are described. We verify the effectiveness of these circuits at self-powered wireless mobile system.
