A Design Basis for Composite Cascode Stages Operating in the Subthreshold/Weak Inversion Regions

A Design Basis for Composite Cascode Stages Operating in the Subthreshold/Weak Inversion Regions

Composite cascode stages have been used in operational amplifier designs to achieve ultra-high gain at very low power. The flexibility and simplicity of the stage makes it an appealing choice for low power op-amp designs. Op-amp design using the composite cascode stage is often made more difficult t...
