A Wide Range Level Shifter Using a Self Biased Cascode Current Mirror

Tejas S. Joshi | Priya M. Nerkar

Abstract: Now a days demand of portable devices like multimedia devices, cellular phones, etc. are increasing and we are approaching towards handheld devices which are small in size and which requires large battery life. Power consumption has become most important design factor for VLSI circuits and system in low power devices. The Level shifter plays very critical role in low power devices. Level shifter can interface low voltage to high input-output voltage. The level shifter is used to allow communication between different modules without adding any extra supply pin. This level shifter circuit uses self biased cascode current mirror and CMOS logic gate. The simulation and measurement results were verified using a 22-nm technology.
