1. Title of the project
On Chip CMOS Low DropOut
2. Need for the study
increasing need for portable battery solutions has driven low power supply
designs. Regulators are an essential part of the ever-growing family of
portable battery-operated devices which are required to minimize the voltage
variations of the battery to acceptable levels. As a result, demand for SoC
solutions has increased the interest in LDO voltage regulators which is a
consequence of requirement of smaller portable products.
3. Objectives (Bullet points)
the realization of current efficient, low voltage, LDO Voltage Regulator.
Logic to optimise the power consumption.
suitable circuit topologies for the realization of low dropout regulators
working at low input voltages and low quiescent current flow without hampering
4. Literature Review
Review of various fundamental topics requiring for the better
understanding of the various topologies developed over the years including
study of Circuit Analysis, Amplifiers, MosFET, Stability Analysis using Bode
plots. Effects of large external bulky
capacitor used for stability requirements.
5. Work Plan (Include Detailed Methodology with Time Schedule)
Understanding the various shortcomings and limitations imposed by
various topologies designed over the years.
Acquaintance with Software required during the course of the
Developing new methodologies to overcome the existing problems and
thereby, improving the performance.
