Abstract: A voltage level shifter device an input stage and an output stage. The input stage is configured to lower one of the first and second output terminals to the low level according to the level of the input voltage. A latch circuit includes a first branch having a first PMOS transistor and a second PMOS transistor coupled in series coupled between a shifted-high-level voltage supply terminal and the first output terminal and a second branch having a third PMOS transistor an a fourth PMOS transistor coupled in series between the shifted-high-level voltage supply terminal and the second output terminal. The first output terminal is a gate of the second PMOS transistor and to a gate of the third PMOS transistor. The second output terminal is coupled a gate of the fourth PMOS transistor and to a gate of the first PMOS transistor.

Abstract: A circuit includes a voltage comparator with an output, a first input and a second input, the first input being coupled to a first reference voltage terminal. An operational transconductance amplifier has an output coupled to the second input of the voltage comparator, an inverting input coupled to the output of the operational transconductance amplifier, and a non-inverting input coupled to a second reference voltage terminal. A filter capacitor is coupled in series between a power supply terminal and the second input of the voltage comparator.
