摘要：

The integration of the three protection circuits namely, over-temperature, over-current, and over-voltage protection circuits for DC-DC Converter is implemented. The over-temperature protection circuit activates whenever the device temperature reaches 150 degrees C. Over-current condition is reached when current is equal to or more than 500mA which initializes the over-current protection circuit. An improved sensing circuit, which utilizes a gate driver, is implemented to boost its efficiency without using a conventional operational amplifier. When the converter produces an output voltage greater than the specified voltage requirement, the over-voltage protection circuit turns off the converter. The chip core design has a total area of 0.0137 mm(2) and implemented in TSMC 90nm CMOS technology. All expected outputs are achieved based on the simulation results.
