Abstract

By means of a complementary metal oxide silicon (CMOS) circuit, voltage is controlled on an n-channel transistor which is used as a pass device and voltage limiter. The circuit provides full high voltage supply Vdd switching levels for CMOS input levels and requires no clocked inputs, while protecting against inputs higher than Vdd.
