A low dropout (LDO) regulator is designed in this paper. By adopting a slew rate enhancement circuit, the slew rate of the LDO output is obviously improved when the load current is suddenly switched from low to high. Moreover, employing a simple bias circuit, the architecture of the LDO regulator is simple, and can be fabricated by conventional CMOS(More)
By adopting the technique of pre-regulator, a high PSRR and low temperature coefficient piecewise-linear bandgap reference (BGR) is designed for analog and mixed-signal application in this paper. The piecewise-linear BGR with pre-regulator, which is analyzed and simulated in SMIC 0.18μm CMOS process, has simple circuit architecture. Simulation results show(More)
