(English Abstract)
A reference voltage generator which is insensitive to PVT (process-voltage-temperature) variation necessary for NVM memory IPs such as EEPROM and MTP memories is designed in this paper. The designed BGR (bandgap reference voltage) circuit based on MagnaChip¡¯s 0.18¥ìm EEPROM process uses a low-voltage bandgap reference voltage generator of cascode current -mirror type with a wide swing and shows a reference voltage characteristic insensitive to PVT variation. The minimum operating voltage is 1.43V and the VREF sensitivity against VDD variation is 0.064mV/V. Also, the VREF sensitivity against temperature variation is 20.5ppm/oC. The VREF voltage has a mean of 1.181V and its three sigma (3¥ò) value is 71.7§Æ.
