WebMar 1, 2024 · Power Supply Rejection (PSR) is a performance metric that measures the LDO’s ability to reject noise. Improving PSR has been the focus of many research groups. However, the state of the art does not recognize the best PSR enhancement schemes and collate them under comparable grounds. WebSep 1, 2024 · The LDO regulator is an important power management module that provides noise-free constant supply voltage to various sub-systems of system-on-chip (SoC). The design of a low power, stable, noise-free cap-less LDO regulator with good voltage regulations and fast transient responses with edge time below is challenging.
