Effects of Fabrication Parameters and Operating Temperature on CDS Thin Film Electronic Properties
A stable and efficient Low-Dropout Regulator (LDO) is reported in this paper, with 1A output current capability.
The LDO converts a 1.5V input to 1.2V output. It uses a two-stage amplifier to achieve large DC gain. An output capacitor is
used to provide the high PSRR. Compensation capacitor is added to ensure stability. The IC is fabricated using 130nm
CMOS technology node and the measurement results are presented. Line regulation and load regulation of LDO are
measured to be 6.4mV/V and 5mV/A respectively.
