Abstract:
1. A diode string voltage adapter, comprising: a substrate of a first conductive type; and a plurality of diodes formed in the substrate, each diode including: wherein the plurality of diodes are serially coupled to each other having a beginning diode and an ending diode, the first heavily doped region of the beginning diode of the plurality of diodes is configured to be coupled to a first voltage, the second heavily doped region of each diode of the plurality of the diodes is configured to be electrically coupled to the first heavily doped region of a next diode of the plurality of diodes, the second heavily doped region of the ending diode of the plurality of diodes is configured to provide a second voltage, and the deep well region of each diode is configured to be electrically floated, during operation of the diode string voltage adapter.
