Biography

Philipp Niemann (Member, IEEE) received the Diploma degree in mathematics and the Ph.D. degree in computer science from the University of Bremen, Bremen, Germany, in 2012 and 2016, respectively.,He worked with the Group for Computer Architecture, University of Bremen under the supervision of Prof. Dr. R. Drechsler and Prof. Dr. R. Wille. In 2017, he joined the Cyber-Physical Systems Department, German Research Center for Artificial Intelligence, Bremen. He published several papers on international conferences, such as ASP-DAC, DATE, RC, MEMOCODE, and MoDELS. His research interests are in the design of reversible and quantum circuits with a focus on decision diagrams, as well as in the verification of formal models.(Based on document published on 3 March 2020).

Least squares approximation-based ROM-free direct digital frequency synthesizer

Ching-Hua Wen;Huai-Yi Hsu;Hung Yang Ko;An-Yeu Wu

2004 IEEE International Symposium on Circuits and Systems (ISCAS)
Year: 2004 | Conference Paper |
This paper describes a new design approach and an architecture for a direct digital frequency synthesizer (DDFS) based on least square (LS) approximation. It is shown that the architecture can be implemented as a low-cost, low-power, feedforward, and easily pipelineable datapath. A prototype IC has been designed and fabricated in TSMC 0.25 /spl mu/m CMOS technology. The IC produces 14-bit sine and...Show More

Implementation of a programmable 64/spl sim/2048-point FFT/IFFT processor for OFDM-based communication systems

Jen-Chih Kuo;Ching-Hua Wen;An-Yeu Wu

2003 IEEE International Symposium on Circuits and Systems (ISCAS)
Year: 2003 | Conference Paper |
Cited by: Papers (8)
Orthogonal Frequency Division Multiplexing (OFDM) system is famous for its robustness against frequency selective fading channel. The Fast Fourier Transform (FFT) and Inverse FFT (IFFT) processor ire used as the modulation/demodulation kernel in the OFDM systems. The sizes of FFT/IFFT processors are varied in the different applications of OFDM systems. In this paper, we design and implement a prog...Show More
