Abstract:
In one embodiment of an integrated circuit, the integrated circuit includes a power transistor with a power control terminal, a first power load terminal and a second power load terminal. The integrated circuit further includes an auxiliary transistor with an auxiliary control terminal, a first auxiliary load terminal and a second auxiliary load terminal. The first auxiliary load terminal is electrically coupled to the power control terminal. The integrated circuit further includes a capacitor with a first capacitor electrode, a second capacitor electrode and a capacitor dielectric layer. The capacitor dielectric layer includes at least one of a ferroelectric material and a paraelectric material. The first capacitor electrode is electrically coupled to the auxiliary control terminal.
