The circuit was slightly modified by Alfonso Urqu?a of the Universidad Nacional de Educaci?n a Distancia in Madrid from the original circuit proposed by Clauß and Schneider. Alfonso tied the bulk of the two p-channel MOSFETs to the high voltage (Vdd) instead of the ground, as the original circuit wouldn't simulate correctly for any modeling levels higher than 0.
