ABSTRACT:
A bias circuit, which generates a bias voltage, has a first MOS transistor coupled between a first reference voltage terminal and a voltage dividing node and a second MOS transistor coupled in parallel with the first MOS transistor. The first MOS transistor may have a first ON-state resistance, and the second MOS transistor may have a second ON-state resistance which is lower than the first ON-state resistance. Furthermore, the bias circuit has a resistance circuit coupled between the voltage dividing node and a second reference voltage terminal and a voltage generator coupled with the first node. The voltage generator outputs the bias voltage in dependence upon an electrical potential on the voltage dividing node.
