“…The calculation of figure of merit (FOM) is widely adopted by researchers and acts as a collective measure of all other performance parameters. The most established equation for calculating FOM is included in Equation (7), which is adopted by many researchers [19][20][21][22][23]45,47,48,[51][52][53][54][55][56][57][58]60,62]. Moreover, several methods of evaluating FOM is presented by authors to signify their design performances, which are added in Equation ( 8) [25], Equation (9) [44], Equation (10) [58], Equation (11) [59], Equation (12) [51], and Equation ( 13) [48].…”

“…The FOM of capless LDO can also be calculated [62] using Equation (7) where total capacitance is equal to output load capacitance and on-chip capacitance is zero. Moreover, researchers have proposed the FOM equation for comprehending the minimum channel length [48] and output power at which ripple is present [25] to reflect the power consumption and active area performance, while others mentioned those parameters separately.…”

Systems-on-Chip’s (SoC) design complexity demands a high-performance linear regulator architecture to maintain a stable operation for the efficient power management of today’s devices. Over the decades, the low-dropout (LDO) voltage regulator design has gained attention due to its design scalability with better performance in various application domains. Industry professionals as well as academia have put forward their innovations such as event-driven explicit time-coding, exponential-ratio array, switched RC bandgap reference circuit, etc., to make a trade-off between several performance parameters such as die area, ripple rejection, supply voltage range, and current efficiency. However, current LDO architectures in micro and nanometer complementary metal–oxide–semiconductor (CMOS) technology face some challenges, such as short channel effects, gate leakage, fabrication difficulty, and sensitivity to process variations at nanoscale. This review presents the LDO architectures, optimization techniques, and performance comparisons in different LDO design domains such as digital, analog, and hybrid. In this review, various state-of-the-art circuit topologies, deployed for the betterment of LDO performance and focusing on the specific parameter up-gradation to the overall improvement of the functionality, are framed, which will serve as a comparative study and reference for researchers.
