Aishwarya is working on the Columbia FlexICoN project,which is the ” Full-duplex wireless from Integrated Circuits to Networks” project. She will be programming the interface to the self-interference cancellation circuit. Also, she would be implementing a OFDM PHY layer and other such schemes using a software defined radio platform with a programmable FPGA module in it. The group aims to make the full duplex communication more efficient and fast..
I worked on designing an “Evaluation Board for a non-magnetic CMOS based Circulator”. Non-reciprocal devices such as circulators have immense application in communication, radar, imaging and sensing. Such devices are mostly made from magneto-optical materials which are bulky, expensive and they cannot be easily integrated on a CMOS based integrated circuit.
Recently, non-magnetic CMOS based circulators have been demonstrated and they have a lot of potential.
The designed evaluation board, which provides an interface to use this new circulator, will be sent to other research groups so that they can easily experiment with the circulator for new applications.
