Title: "State of Art Digital-to-Analog
Converter Design in Nano-meter CMOS Process"
Abstract:
Digital to Analog converter
(DAC) is an essential building block in applications ranging from audio to
RF. Today’s popular devices such as smart phones and tablets require
DACs integrated in Nano-meter digital CMOS process to able to interact with
the real world. In audio signal chain, very tight requirements on linearity
and noise performance are enforced. On the radio transmitter signal chain,
speed and band width become the critical issue. DACs are also critical in
Analog-to-Digital design that uses popular Sigma-Delta Conversion techniques.
ADC’s performance is as good as the feedback DAC’s performance. This talk will present the issues
faced designing highly linear, high dynamic range and band-width DACs
especially when using imperfect CMOS processes. It will cover the physical
root causes of performance degradation. The key to any high quality and
robust system lies in the ability to analyze and optimize at all levels of
design. So we will show the state of art in dealing with these problems using
smart signal processing, architecture design and circuit design. Speaker:
Rahmi Hezar, Kilby Lab, Texas Instruments, Inc. Biography:
Dr. Rahmi Hezar
received his B.Sc. degree in electrical and electronics engineering from
Bogazici University, Istanbul, Turkey in 1993. He completed his M.Sc. and
Ph.D. degrees in electrical engineering from Georgia Institute of Technology,
Atlanta, GA in 1994 and 2000 respectively, with specialization in digital
signal processing.
He joined Texas
Instruments Wireless Business Unit in 2000, initially working to develop DSP
cores for cellular phones. He later became part of the first CMOS analog
mixed signal integration team in TI where he developed high speed ADC and DAC
architectures for a variety of applications ranging from Radio to Audio. For
the past 2 years he is part of the Kilby Labs in TI working on Digital
Transmitters and Power Amplifiers. Dr. Hezar’s expertise is in
continuous time sigma delta ADCs/DACs, Power Amplifiers, mixed signal
processing, system design and modeling. He has 25 U.S. patents and 20 IEEE
conference/journal publications.
