dc.description.abstractPower regulators are essential in ensuring stable output for electronic systems by controlling voltage levels. Linear regulators, such as low dropout (ldo) regulators, fixed linear regulators, and shunt regulators, adjust resistance to maintain stable voltages, commonly used in rf applications, audio circuits, and precision analog systems. Switching regulators, including buck and boost converters, efficiently convert voltage by rapidly switching a transistor, typically used in power supplies where noise sensitivity is lower. In this work, a high-efficiency multi-voltage domain (mvd) integrated buck-ldo regulator with a combined compensation scheme is proposed. The mvd buck-ldo operates with a 4.0 v supply headroom and regulates four voltage domains (1.8 v to 3.0 v) with an efficiency of 85.24%. An integrated demultiplexer controller consumes just 42 nw. The design minimizes external components, requiring only a single inductor and capacitor, with a 500 khz clock generator. A single 1.25 v bandgap reference supports both buck and ldo functions.
