Abstract:
A sensing circuit includes: a follower transistor, having a control terminal; a follower terminal for connection to a load; a bias-current generator, coupled to the follower terminal; and a feedback stage, configured to control the bias-current generator as a function of an input signal on the control terminal of the follower transistor.
