Abstract :
CMOS under-voltage lockout (UVLO) circuit configured Schmitt trigger was fabricated and tested. The UVLO circuit consist of current source inverter, Schmitt trigger, delay circuit, and waveform shaper of the output. The tested result shows that the UVLO has size of die was 136 μm × 85 μm, turn on and off voltage was at 1.85V and 1.70V, respectively. The fabrication process was Magna/Hynix CMOS 0.35 μm process and supply voltage was 3.3V. Power dissipation of the UVLO was 0.18mW.
