Abstract
Apparatus are provided for a stacked cascode current source. An apparatus is provided for an electrical device comprising an input node and an output node. A first transistor stack is coupled to the input node. The first transistor stack includes a first transistor and a second transistor. A drain terminal and a gate terminal of the first transistor are coupled to the input node. A drain terminal of the second transistor is coupled to a source terminal of the first transistor and a gate terminal of the second transistor is coupled to the input node. A second transistor stack coupled to the first transistor stack and the output node to create a current mirror for the first transistor stack.
