Abstract:
A low voltage multi-stage amplifier is described. The low voltage multi-stage amplifier includes one or more prior stages. The low voltage multi-stage amplifier also includes a supply stage. The low voltage multi-stage amplifier further includes an output stage that operates with a supply voltage as low as a sum of a threshold voltage of a first transistor in the output stage and a saturation voltage of a second transistor of the supply stage. The supply stage supplies the output stage.
