ABSTRACT:
There is disclosed a reference voltage generator in a semiconductor device comprising first and second power ports to which first and second power supplies are independently provided, a filter connected between the first and the second power ports for filtering a component of the first power supply from the first power port to provide a filtered power supply to the inner power supply node, a first pull-up transistor having a current route formed between the inner power supply node and a predetermined first connection node and a control port connected to a predetermined second connection node, a second pull-up transistor having a current route formed between the inner power supply node and the second connection node and a control port connected to the second connection node, a third pull-up transistor having a current route formed between the inner power supply node and a reference voltage output node and a control port connected to the second connection node, a first pull-down transistor having a current route formed between the first connection node and the second connection node and a control port connected to the first connection node, a second pull-down transistor having a current route formed between the second connection node and the second connection node and a control port connected to the first connection node having current restricting resistance, and a loading unit formed between the reference voltage output node and the second power supply port.
