ACADEMIC PROJECTS:
1. Research: Designed, simulated and taped-out “Efficient Boost Converter Design of a Multi-String LED
Driver.”
• Input Voltage = 2.8V-4.2V, Output Voltage = 5.4V, Load Current = 100mA, 20mA for each string.
• Output voltage set by PFM Hysteretic Controller technique.
• Both voltage mode and current mode control loop used with synchronous Boost Converter.
• Current in LED strings matched using regulated cascode current matching circuit.
• Hysteretic comparator based LTA circuit used to select the minimum voltage between LED strings.
• Inductor Current ON and OFF time tracked through Current Sensing circuit.
• Dimming function is performed using PFM dimming technique.
Designed and simulated a:
2. Power Management IC with the help of 2-Buck Converter, a Boost Converter, a LDO Regulator and a
Bandgap Reference circuit.
• A boost converter was used to drive output voltage of 2V with switching frequency of 2MHz.
• Buck converters used to drive output voltages of 1.2V and 1.8V with switching frequency of 2MHz.
• LDO Regulator drove the output voltage of 1.5V with the switching frequency of 2.5MHz.
• PWM voltage feedback control loop drove the output voltage.
• IC supplies power to LED driver, Audio codec and CPU core.
3. LDO Regulator circuit
• Input voltage = 1.8V, Output voltage = 1.5V and dropout voltage = 85mV.
• Achieved Phase Margin was 88° and Gain Margin was 24dB.
• Obtained load regulation of 4mV and line regulation of 15mV.
4. Folded Cascode Amplifier
• Designed for Gain Bandwidth Product of 10MHz and bias current of 5µA.
• Load capacitance=12pF and slew rate was 34mV/s.
5. Digital Phase Locked Loop (DPLL)
