Abstract
The present invention proposes a voltage-clipping device utilizing a pinch-off mechanism formed by two depletion boundaries. A clipping voltage of the voltage-clipping device can be adjusted in response to a gate voltage; a gap of a quasi-linked well; and a doping concentration and a depth of the quasi-linked well and a well with complementary doping polarity to the quasi-linked well. The voltage-clipping device can be integrated within a semiconductor device as a voltage stepping down device in a tiny size, compared to traditional transformers.
