Apparatuses and methods for providing bias signals in a semiconductor device are described. An example apparatus includes a power supply configured to provide a supply voltage and further includes a bias circuit coupled to the power supply to produce a bias current. The bias circuit is configured to decrease the bias current as the supply voltage increases from a first value to a second value. The bias circuit continues to decrease the bias current as the supply voltage further increases from the second value in a first operation mode. The bias circuit also prevents the bias current from decreasing against a further increase of the supply voltage from the second value in a second operation mode.
