Active load for an N channel logic network

摘要

An active load (12) is provided for an N channel logic network (10). The active load (12) includes a P channel device (28) coupled to the output node (14) of the N channel network (10). A clock circuit (16) of the active load (12) determines whether the N channel network (10) is in a steady state or a switching mode. If the N channel network (10) is in a switching mode, an intermediate voltage level, Vbias, is applied at the gate of the P channel device (28) to facilitate fast switching at the output node (14) with low quiescent power consumption and without compromising compact semiconductor layout.
