Abstract
The present disclosure provides a varying high voltage source implemented with low voltage domain electronic components that are less costly to manufacture. According to one aspect, the present disclosure provides a high voltage circuit apparatus comprising a pull up resistance module, a plurality of cascode cell stages, a first of the cascode cell stages being coupled to the pull up resistance module, a low voltage domain current sink module coupled to a last of the cascode cell stages, and a clamping voltage source coupled to the last of the cascode cell stages. The circuit apparatus is devoid of high-voltage transistor components.
