A Low Noise CMOS Low Dropout Regulator with an Area-Efficient Bandgap Reference

In a low dropout (LDO) linear regulator whose reference voltage is supplied by a bandgap reference, double stacked diodes increase the effective junction area ratio in the bandgap reference, which significantly lowers the output spectral noise of the LDO. A low noise LDO with the area-efficient bandgap reference is implemented in 0.18 μm CMOS. An effective diode area ratio of 105 is obtained wh...

Low Power Low Noise CMOS Chopper Amplifier

AbstractChopping is a proficient way to reduce the low frequency offset and 1/f noise in amplifiers. In this paper, a low power low noise CMOS chopper amplifier is presented. It is composed of a two stage amplifier. The first stage’s high output impedance and the equivalent Miller capacitance of the second stage constitute together a low pass filter, which reduces the power consumption. The cir...

Noise Minimization for Low Power Bandgap Reference and Low Dropout Regulator Cores

This paper describes the techniques to design low power series low dropout regulators (LDO) with low output noise and high power supply rejection (PSR). The noise analysis of the bandgap reference is critical to the linear regulator’s output noise, since it represents the main source of noise. The necessary trade-offs that a designer faces are discussed according to the demands of modern IP cor...
