Abstract
A high voltage digital output driver with dynamically biased cascode transistors is disclosed. The cascode transistors are dynamically self-biased via capacitors from the output voltage. The dynamic self-biasing doesn't require any switching means. The output-voltage can be increased by adding additional self-biased cascode transistors. The static current consumption in low-state for each individual driver on a same chip is minimal because only one resistor string consuming static current is required for all similar output drivers.
