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.

Claim (Index 16):
The device of  claim 12 , further comprising a gain controller, the gain controller comprising:\n a split cascode stage comprising: a first controllable switch coupled to the first voltage supply rail and having a control terminal; a second controllable switch coupled to the second voltage supply rail and having a control terminal coupled to the control terminal of the first controllable switch of the split cascode stage; multiple cascode circuit paths coupled between the first and second controllable switches of the split cascode stage, each of the multiple cascode circuit paths of the split cascode stage comprising a pair of controllable switches; respective resistors coupling together the control terminals of the controllable switches of the cascode circuit paths that are coupled to the first controllable switch of the split cascode stage and coupling together the control terminals of the controllable switches of the cascode circuit paths stage that are coupled to the second controllable switch of the split cascode stage; and feedback paths coupled to the control terminals of the first and second controllable switches of the split cascode stage and to respective feedback points between the pairs of controllable switches of the cascode circuit paths in the split cascode stage; and a current mirror and amplifier stage comprising: a variable current source; a current mirror coupled to the variable current source and to a control terminal of a controllable switch, of the pair of controllable switches of one of the cascode circuit paths in the split cascode stage, which is coupled to the second controllable switch of the split cascode stage; and an amplifier coupled to the current mirror, the amplifier having an output coupled to a control terminal of a controllable switch, of the pair of controllable switches of the one of the cascode circuit paths in the split cascode stage, which is coupled to the first controllable switch of the split cascode stage, the amplifier further having inputs coupled across one of the feedback paths that is coupled to the control terminals of the first and second controllable switches of the split cascode stage and to one of the respective feedback points between the pairs of controllable switches of the cascode circuit paths in the split cascode stage, wherein gain control signals to control the pair of controllable switches of the one of the cascode circuit paths in the split cascode stage are generated at the control terminals of the pair of controllable switches of the one of the cascode circuit paths in the split cascode stage.
