Design of a capacitor-less LDO with high PSRR for RF energy harvesting applications

摘要: This paper presents a capacitor-less low-dropout (LDO) regulators with high power supply rejection ratio (PSRR) for powering RF energy harvesting applications. The band-gap reference (BGR) in the proposed LDO utilizes current mode regulator to isolate circuitry from variations and noise. achieves post-layout simulated PSRR of −85.67dB at 1 kHz. is implemented standard 180nm CMOS technology die size 378μm × 390μm.
