Abstract :
This work presents a CMOS voltage reference built within a negative LDO processed in a double-metal 0.8 μm CMOS technology. The reference consumes 12 μA, and delivers a stable output voltage of -1.2 V. Power supply rejection ratio is 86 dB at low frequencies, while TC is within ±50 ppm/°C, and un-trimmed VREF spread 60 mV (±3σ).
