Abstract

Linear regulator is an area-efficient component for voltage regulation that could achieve excellent power supply ripple rejection. With no switching activities as compared to a switched-inductor or switched-capacitor power converter, it can serve as a well-controlled power source for digital and especially noise-sensitive analog circuits. It is very suitable for miniature and low-power systems, such as wireless power receivers for portable and implantable applications. This chapter starts with the basic topologies of linear regulators followed by control loop design. Various circuit techniques are demonstrated through the design of two fully-integrated examples that were implemented in 65 nm and 28 nm bulk CMOS processes, respectively.
