IC Design

I have developed several prototype ICs to demonstrate various design solutions at Georgia Tech and before coming to Georgia Tech.

Designs at Georgia Tech:

• Topic 1: Energy Harvesting from Low input voltage sources and Power Delivery for low power Electronics:

Demonstrated solutions to several key challenges in low voltage energy harvesting, from both circuit and system perspectives prototype ICs. Following are the details of the prototype ICs.

# 1-A: Improving Energy Efficiency through bias gating technique that reduces the self-power consumption without sacrificing performance.

# 1-B:Improving conversion ratio through cascaded operation which enables extremely low input energy harvesting.

#1-C: Increasing the duty cycle of the oscillator which plays vital role in determining the conversion ratio in switching regulators.

• Topic 2: On-chip Conversion of High-voltage using Low-voltage Transistors

#Primary contribution is a hybrid power converter and voltage regulator which consists of a switched capacitor down converter followed by an inductive buck regulator. The design features stress management for higher than breakdown voltage, load dependent variable frequency PWM operation and adaptive slope compensation circuit for current mode buck regulator.
