A 200 mA CMOS low-dropout regulator with double frequency compensation techniques for SoC applications
This paper presents a 200 mA low-dropout (LDO) linear regulator using two modified techniques for frequency compensation.One technique is that the error amplifier uses a common source stage with variable load,which is controlled by the output current,is served as the second stage for a stable frequency response.The other technique is that the LDO uses a pole-zero tracking compensation technique at the error amplifier to achieve a good frequency response.The …查看全部>>
