摘要

This paper presents an output-capacitor-less low-dropout regulator (LDO) with nested miller compensation and bulk-driven techniques. The proposed LDO has been fabricated in TSMC 90 nm CMOS technology. The nominal supply voltage of the LDO is 1.8 V and the output voltage is 1.2 V. Bulk-driven technique is used to improve the power supply rejection Ratio (PSRR), which are −64 dB at 100 kHz and -24 dB at 25 GHz. It occupies 160 μm × 85 μm of chip area. Measurement results show the drop-out voltage is 200 mV at the maximum output current of 40 mA.
