The designers of these circuits based them on the same concept: a fully integrated, single-die-IC switching regulator and a micropower operational amplifier.

些电路的设在设时都有同样的观念：完整的单模式集成电路继电和功率运放。

MEMS will be one of the most important realm of science in 21th century,and micropower which is a branch of MEMS directly relates to development of MEMS in some applied realm.

机电系统(MEMS)将是21世纪最重要的研究领域之,能源件是MEMS其中个重要分支,其发展直接关系到MEMS在某些领域中的应用。
