Semiconductor device

摘要

A semiconductor device comprises a first current mirror circuit (101) which has an input terminal (101I) and an output terminal (101O), a second current mirror circuit (102) which has an input terminal (102I) and an output terminal (102O) wherein the input terminal (102I) is coupled with the output terminal (101O) wherein the output terminal (102O) is coupled with said input terminal (101I) and a start-up circuit (103) which supplies current to input terminal (102I) based on voltage on the input terminal (101I).
