A proposed under-voltage lockout of compensated temperature coefficient threshold voltage without comparator is presented in this paper. The circuit achieves stability of threshold voltage without utilizing extra band gap reference voltage source and voltage comparator. In the temperature range of from -40°C to +125°C, variation of only 30mV of the threshold voltage occurs. The under-voltage lo...

The design and application of level shifter circuit which is based on single power supply is presented in this paper different from conventional level shifter circuitry. A level shifter may be used to shift any voltage level to a desired level without any leakage current. To reduce the supply routing and layout congestion within the chip whenever level shifting is needed for different voltage i...
