Abstract
SummaryA low‐dropout regulator (LDO) based on dual cross‐coupled current mirrors is reported in this paper. The proposed dual cross‐coupled current mirrors boost output signal current such that the loop gain of LDO is significantly enhanced, and the error amplifier in LDO retains single‐pole property within the loop bandwidth of LDO. Designed in a 65‐nm CMOS process and operating at a minimum of 1‐V supply, the proposed LDO provides a 0.8‐V output and delivers a maximum of 50 mA. The figure‐of‐merit of the proposed LDO is 8.9 ps.
