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. As a result of the reduced variation in the on resistance, attenuation of the data signal is reduced.
