中文摘要：

在芯片上电过程中，需要复位电路提供一个复位信号，保证系统正常启动。为了解决传统电路中起拉电压和复位时间较难控制等问题，提出一种利用反相器翻转电压设置起拉电压、电容控制复位时间的新型结构。该上电复位电路在MXIC0．5μmCMOS工艺上得以验证实现。测试结果表明在正负电源分别为0V和-5V的情况下，电路的起拉电平为-4．5V，复位时间为3．44ms，满足工程要求。

英文摘要：

During the process of charging the chip with electricity, a reset signal of the pow- er-on reset circuit is needed to guarantee normal work of the chip. In order to solve the problems in traditional power-on reset circuits such as hard to control the pull level and reset time and so forth, a new structure which uses the inverter trigging signal to set pull level and control the re- set time with the capacitances was proposed in this paper. This power-on reset circuit was veri- fied in MXIC 0. 5 μm CMOS technology. And the test result indicated that the circuit pull level is -4.5 V, and the reset time is 3.44 ms with 0 V positive and -5 V negative power. So this cir- cuit can meet the engineering requirements well.
