An electronic device includes a transistor having a body and a body biasing circuit. The body biasing circuit includes a threshold estimator circuit to estimate a threshold voltage of the transistor and a comparison circuit to compare the threshold voltage of the transistor to a reference threshold voltage and to generate a comparison signal based thereupon. A bias adjust circuit generates a body biasing voltage that biases the body of the transistor as a function of the comparison signal, the body biasing voltage being a voltage that, when applied to the body of the transistor, adjusts the threshold voltage thereof to be equal to the reference threshold voltage.
