The present disclosure relates to methods and circuits to lowering the signal range of switching or logic circuits below supply range. The circuits may have one or more stages. The supply levels can be set individually for each stage. This may realize amplifiers/attenuators, both digitally and analogically controlled, based on progression and/or modulation in the supply range from stage to stage. A chain of stages can provide the desired power gain by setting the supply progression according to the nature of the incoming signals. The signal levels are lowered by generic device networks comprising voltage sources providing voltages independent of currents flowing through. Decoupling the signal amplitude from DC biasing allows for the signal swing to be lower than threshold voltages of the active devices.
