ABSTRACT:
A voltage detector for determining the high or low status of a power supply output voltage, including a front-end detector and an inverting amplifier. The front-end detector includes a number of NMOS and PMOS transistors which constitute active loads. The voltage detector is inherently independent of device fabrication condition changes, as well as on the temperature variations.
