A new circuit topology for floating High Voltage level shifters

A novel and simple circuit topology is presented for high-speed, floating, high voltage level shifters. It uses a current mirror plus latch circuit composed of two inverters. Simulations based on AMS 0.18 μm High Voltage (HV) CMOS Technology show this circuit to combine high speed, low power dissipation, and small layout area. The simulation results show the propagation delay to be below 150 ps for a transition from 1.8 V to 13.8 V.
