1. Title of the project On Chip CMOS Low DropOutVoltage Regulator 2. Need for the study Theincreasing need for portable battery solutions has driven low power supplydesigns. Regulators are an essential part of the ever-growing family ofportable battery-operated devices which are required to minimize the voltagevariations of the battery to acceptable levels. As a result, demand for SoCsolutions has increased the interest in LDO voltage regulators which is aconsequence of requirement of smaller portable products.
3. Objectives (Bullet points) · Focus onthe realization of current efficient, low voltage, LDO Voltage Regulator.· ControlLogic to optimise the power consumption.· Developsuitable circuit topologies for the realization of low dropout regulatorsworking at low input voltages and low quiescent current flow without hamperingits performance. 4. Literature Review Review of various fundamental topics requiring for the betterunderstanding of the various topologies developed over the years includingstudy of Circuit Analysis, Amplifiers, MosFET, Stability Analysis using Bodeplots. Effects of large external bulkycapacitor used for stability requirements. 5.
Work Plan (Include Detailed Methodology with Time Schedule) Understanding the various shortcomings and limitations imposed byvarious topologies designed over the years.Acquaintance with Software required during the course of theproject.Developing new methodologies to overcome the existing problems andthereby, improving the performance. 6.
