Abstract: Various implementations described herein may refer to level shifter circuitry using current mirrors. For instance, in one implementation, a level shifter circuit may include a latch circuit configured to receive an input signal, where the latch circuit includes a plurality of transistors configured to generate an output signal based on the input signal. The level shifter circuit may also include a first current mirror circuit coupled to the latch circuit. The level shifter circuit may further include a second current mirror circuit coupled to the latch circuit, where the first current mirror circuit and the second current mirror circuit are configured to drive the output signal from a transient state voltage level to a steady state voltage level.
