Dr. Anuj Batra

Dr. Anuj Batra works on high-speed digital communications technologies at Texas Instruments (TI). He received his PhD from the Georgia Institute of Technology in 2000, and since then, has been working with TI. Dr. Batra is currently the technical leader for TI’s standardization activities related to wireless LAN.

In 2002, Dr. Batra helped start an ultra wideband (UWB) development effort within Texas Instruments. He led a small TI development team that created a wireless high-speed technology, based on a multi-band OFDM approach, which uses the Ultra Wideband (UWB) spectrum. Their approach is novel in that it uses a bandwidth that is 75 times greater and power levels that are 1000 times smaller than what is typically used in systems today. Such an approach enables a high-speed scalable wireless technology that can transmit data rates of 110 Mb/s at a distance of 10 meters (33 feet), in multi-path environments.

In addition to developing the technology, Dr. Batra also served as the primary author for the UWB physical layer specification that describes this new technology. In addition, he helped to create the Multi-band OFDM Alliance (MBOA), which promotes, develops, and ensures interoperability of devices based on Texas Instruments’ initial specification. This organization later merged with the WiMedia Alliance to produce a single entity for the design, development and certification of UWB products based Multi-band OFDM. To date, over 100 companies have joined the MBOA/WiMedia Alliance and are developing products based on TI’s initial physical layer specification.

Dr. Rajit Manohar

As an internationally recognized pioneer in asynchronous semiconductor design and implementation, Dr. Rajit Manohar has spent over ten years working in the field of asynchronous VLSI.

In 2004, he co-founded Achronix Semiconductor Corporation, and serves at its CTO. Dr. Manohar is also an Associate Professor of Electrical and Computer Engineering at Cornell University. He was the recipient of an NSF CAREER award as well as numerous teaching awards at Cornell.

Dr. Manohar’s team has built faster and more energy efficient computer chips by removing the onboard clock present on the chip. The clock synchronizes the different functions of a computer chip, causing the fastest operations not to pass on their data until the slowest have finished. Instead of a separate clock network carrying a global timing signal, Dr. Manohar’s chips use short wires to carry signals that alert successive operations when the previous operations have finished. These chips were shown to be 10 times more energy efficient than previous clockless chips.

Dr. Manohar was selected by MIT’s Technology Review magazine in 2005, as one of the world’s “Top Innovators Under 35 in Science and Engineering”. Dr. Manohar received his B.S., M.S., and Ph.D. in Computer Science from the California Institute of Technology.
