ABSTRACT:
An integrated circuit, includes an output stage with an input which is coupled to a first and a second gate of an NMOS transistor and a PMOS transistor, respectively, and an output which is connected to a first and a second supply terminal via the PMOS transistor and the NMOS transistor, respectively. The output is coupled to the first gate via a series connection of a Miller capacitor and a switching circuit. The Miller capacitor limits the rate of increase of the voltage on the output, thus preventing interference. The switching circuit is rendered non-conductive ahead of the switching over from logic low to logic high. This prevents sudden discharging of the Miller capacitor which would otherwise cause interference itself.
