دانلود رایگان مقاله A 65-nm CMOS Low Dropout Regulator Featuring >60-dB PSRR Over 10-MHz Frequency Range and 100-mA Load Current Range

One of the most critical attributes of low dropout regulators (LDOs) in increasingly complex systems on chip (SoCs) is high-power supply rejection ratio (PSRR), not only over a wide frequency range but also over a large load current range. This paper presents an LDO, realized in 65-nm CMOS, featuring >۶۰-dB PSRR over a 10-MHz frequency range and a 100-mA large load current range.
