Academic Projects

Design of Charge Pump

Design a circuit to get 2.4V output voltage by doubling the 1.2V input voltage using 130nm model.

Design of Switch Mode Buck DC-DC Power Supply

Design the buck converter with the input 1.8V and desired output 1.2V using 130nm model. Load current is higher than 50mA.

Design of Low Dropout Regulator for portable applications using Cadence

0.35um technology is used to design the LDO consisting of error amplifier, buffer stage and pass device with stability under

different load conditions. Advantages of this circuit are 0.2V Dropout voltage, low no load quiescent current 33.58uA and good

load regulation 108.3uV/mA.

Design and Simulation of fully differential two stages operational amplifier using Cadence

Design a circuit that with 1.075mW Power Consumption, 69.1dB Low-frequency Gain, 213MHz Unity-gain Frequency, Phase

Margin 62.1degrees, and other performances like Slew Rate, CMRR, PSRR, DC Output.

Design of 8 bit ALU

Implemented 8 bit Arithmetic/Logic unit in Verilog using behavioral modeling. Design of standard library cells, layout and spice

simulation using cadence tools for IBM 130nm technology. Run DRC, LVS, QRC and Library characterization using Silicon

Smart ACE. Placement & routing using Encounter, static timing analysis.

Dynamic Modeling and Simulation of a PEMFC-Wind Hybrid Power System using Simulink

This system consists of Power controller, Full cell stack, Electrolyzer module. Through Boost converter and Inverter stage to get

120V AC to the load. This system achieves to reduce the output fluctuation due to wind speed and load variation, to solve the

storage problem of wind power.

Sensorless Vector Control of PMSM Based on MRAS using Simulink

This system has speed loop and current loop. Space Vector PWM used for inverter design. FOC control technique is used. MRAS

is for rotor speed estimation.
