Abstract
A regulated cascode circuit includes a first MOS transistor of a first conductive type, a second MOS transistor of the first conductive type, a third MOS transistor of a second conductive type, a first current source and a second current source. The first MOS transistor is coupled between an output node and a first node. The second MOS transistor having a gate terminal for receiving a bias voltage is coupled between the first node and a second power supply voltage. The third MOS transistor is coupled between the first power supply voltage and a gate terminal of the first MOS transistor. The first current source is coupled between the gate terminal of the first MOS transistor. The second current source is coupled between the first power supply voltage and the output node.
