Abstract
For solar energy calculator, the voltage regulator circuit is composed by three PN junction diodes in series. The design may cause some issue:because of the higher Vf for voltage regulator circuit, the voltage of solar energy battery is too higher to arouse voltage can not release in time when sunlight is strong. These issue will lead to calculator can not work well. This paper improve the design of diode voltage regulator circuit. One PN junction diode be changed to shottky diode by change P+mask. So the Vf get more reasonable range than ever. What is more, the impact is researched on thickness of Ti layer and temperature. Finally, it show that this improvement fit our requirement.关键词
