Abstract: Split cascode circuits include multiple cascode paths coupled between voltage supply rails. Each cascode path includes a pair of controllable switches. A feedback path is provided for at least one of the cascode circuit paths. An active load circuit may also have a split cascode structure. Multiple-stage circuits, for implementation in Trans-Impedance Amplifiers (TIAs) or analog Receive Front-End modules (RXFEs), for example, include multiple stages of split cascode circuits.
