ABSTRACT:
A boost-biased level shifter is described. In the preferred embodiments of the present invention, a voltage divider circuit divides the high voltage applied on the receiver circuit that receives the input signal, a refresh and self-bias circuit maintains and refreshes a bias voltage that is high enough to turn on the transistors in the voltage divider circuit, and a voltage output circuit outputs a signal having the amplitude of a higher power supply source, which is higher than the input signal amplitude. The preferred embodiments can operate at input signals having a lower amplitude. The performance is improved.
