Reference voltage generation circuit |
摘要 |
A start-up section is made up of an input transistor configured to receive at its gate a voltage at a node which varies with the magnitude of a current flowing in one branch of a current mirror in a reference voltage generation section, an inverter for reversing a drain voltage of the input transistor, an output transistor for supplying a start-up current to the reference voltage generation section in response to an output voltage from the inverter, and a current limit transistor serially connected to the input transistor. The current limit transistor receives a reduced gate-source voltage from the reference voltage generation section for limiting a flow of current in the input transistor upon completion of restarting the reference voltage generation section.
