ABSTRACT:
A semiconductor circuit consisting of a dynamic-type circuit and a bias-voltage generating circuit. The bias-voltage generating circuit is comprised of a first bias-voltage generator and a second bias-voltage generator. The first generator absorbs a variable substrate current, the magnitude of which is proportional to the operating frequency of the dynamic-type circuit, while the second generator absorbs a substrate current, the magnitude of which is not proportional to the operating frequency of the dynamic-type circuit. Alternately, both portions of the substrate current may be absorbed via the same circuitry.
