Design of a Novel Power-on-Reset Circuit Based on Power Supply Detector

摘要

A Power-on-Reset circuit of novel simple structure and high reliability is proposed. The circuit has been designed in 0.5um Bipolar CMOS technology. The simulation was performed with 0.5um CSMC process model and Cadence Spectre and the results show that the circuit has a stable and reliable performance. With the differences of supply voltageȁ9;s ramp rate, temperature and process, the change of threshold voltage is in small distribution.
