Abstract
A high-voltage level translator circuit is disclosed that is suitable for monolithic integration. The level translator circuit comprises serially-connected current sources suitably ratioed so that the gating on of one current source causes a limited voltage rise across the other current source, which is ungated. The circuit is suitable for integration in a junction-isolated monolithic pseudo-complementary CMOS format.
