Query: A 100 mA Low Voltage Linear Regulators for Systems on Chip Applications
  Using 0.18 {\mu}m CMOS Technology   A novel design for a low dropout (LDO) voltage regulator is presented and
dedicated to power many sections of a typical cellular handset. However, these
baseband, RF, and audio sections have different requirements that influence
which LDO is most appropriate. After discussion of the specific requirements,
different LDOs are recommended. Also, some LDO design techniques are briefly
discussed to demonstrate how an LDO may be optimized for a specific level of
performance. Cellular phone designs require linear regulators with lowdropout,
low-noise, high PSRR, low quiescent current (Iq), and low-cost. They need to
deliver a stable output and use smallvalue output capacitors. Ideally, one
device would have all these characteristics and one low-dropout linear
regulator (LDO) could be used anywhere in the phone without worry. But in
practice, the various cell phone blocks are best powered by LDOs with different
performance characteristics. This paper provides a new design methodology to
choosing the right LDO to power each cell phone and especially for the Voltage
Phase-Locked loops (VPLLs) blocks. Fabricated in a 0.18 {\mu}m CMOS process,
the measured results show the adopted topology achieves a better phase noise
than the conventional saturation current source. and the spread of the current
limitation (without matching) is 100mA, the VPLLs system demonstrates a phase
noise of 782 nv/sqrtHz at 100-kHz, and 33 nv/sqrtHz at 1 MHz, while quiescent
current 33 {\mu}A from a 2.6 V supply voltage.
