Development of Low Power Low Dropout Regulator with Temperature and Voltage Protection Schemes for Wireless Sensor Network Application

The paper is about the development of low power Low Dropout (LDO) regulator with additional housekeeping blocks including the Thermal Shutdown (TSD) and Undervoltage Lockout (UVLO) circuits as a temperature and voltage protection schemes for WSN application. The design is implemented using Synopsys Custom Designer tool, and the layout is physically verified using Hercules. The maximum power dissipation of the system is 298uW, with current efficiency of 76.77%.
