Abstract
The present invention provides a voltage level shifter architecture applicable for positive and negative voltage shifting, in which a shielding circuit is configured to relax the voltage stress of the transistors in the input stage circuit, and a switching circuit is configured to avoid current leakage. In addition, designing the power domain(s) of the n-well P-type transistors in the voltage-level shifter makes the voltage-level shifter area-efficient and power-efficient or design-flexible and application-adaptive.
