Session Abstract:Power amplifiers in wireless communication systems require high linearity and pre-distortion techniques are required to achieve this without compromising on power efficiency. For this meeting, we have two experts in the field of power amplifier linearization: Dr. John Wood will present an update on new developments in digital pre-distortion and Dr. Rajeev Krishamoorthy will talk about a novel analog pre-distortion technology operating on signals in the RF domain, which has been gaining traction in mid-to-low power cellular base stations as well as several other adjacent markets. Dr. Krishnamoorthy's talk will also cover a family of RF Power Amplifier Linearizers (RFPAL) System-on-Chip (SoC) solutions from Scintera. Dr. Krishnamoorthy will also discuss the applicability of the underlying analog signal processing technology to other markets.

Speaker: Rajeev Krishnamoorthy

Bio: Rajeev Krishnamoorthy is CTO of Scintera Networks. Prior to this, he was founder and CEO of TZero Technologies (acquired by NDS Surgical Imaging), a fabless semiconductor company providing high-performance Ultra Wideband chipsets and digital video solutions. Before founding TZero, Rajeev was VP, Technology at Iospan Wireless (later part of Intel) and helped develop the first commercially available MIMO cellular wireless systems. He began his career at Bell Labs conducting research in communications and data networking, and in the wireless LAN division of AT&T/Lucent in the Netherlands where he played a key role in the development of the earliest WiFi (802.11 and 802.11b) products which enabled the first widely deployed wireless LAN networks.
Rajeev has been an EIR and consultant at Globespan Capital Partners and Tallwood Venture Capital, an advisor and board member of several venture-backed startups, and a Consulting Professor at Stanford University. He earned his PhD from Cornell and his BS from Caltech.
