Abstract
Various example embodiments are directed to methods and circuits for mitigation of on-resistance variation and signal attenuation in transistors due to body effects. In some embodiments, an apparatus includes a transistor configured to provide a data signal from a first one of the source or the drain to the other one of the source or the drain in response to a control signal provided to the gate. A body bias circuit is configured to bias the body of the transistor based on a voltage of the data signal to reduce variation in the on-resistance exhibited by the first transistor. In an embodiment, the apparatus includes body bias transistors and switches and the gates of the body bias transistors are connected to protect the body bias transistors from the effects of electrostatic discharge (ESD) events.
