Abstract :
A cascode current mirror with auxiliary body-driven feedback loop is proposed. Main performance parameters are analytically evaluated and compared to those of a conventional high-swing cascode and of a recently-proposed body-driven topology. Simulations are also provided confirming improvements in the achievable output resistance (important for short channel technologies), DC accuracy, and input dynamic range. Linearity, bandwidth, noise and voltage requirements are substantially the same of the conventional high-swing cascode solution.
