Abstract
A device includes a plurality of high voltage cells (HVC) coupled to a plurality of resistors, and a controller. The plurality of HVC generates an output voltage that is higher than an input voltage to the plurality of HVC. The controller receives a reference voltage and an output voltage from a resistor of the plurality of resistors. The controller generates a signal responsive to a difference between the reference voltage and the output voltage. The controller forms a closed feedback loop with the plurality of HVC and the plurality of resistors. The generated signal is input to the plurality of HVC. A substrate of a resistor of the plurality of resistors is biased to an output of at least one high voltage cell of the plurality of HVC. Output of the at least one high voltage cell is input to another high voltage cell.
