Low-power Digital Filter Using Optimized CSD and Pipelined AU for 24-bit Audio DAC

Autor: Ji Man Cho, Soon-Seob Lee, Sung-Nam Kim, Yun-Mi Song

Publikováno v: 2008 Digest of Technical Papers - International Conference on Consumer Electronics.

A new optimization algorithm of the digital filter over the CSD coefficient is proposed. This method is based on the selective weighting method assigning more number of operations to some coefficients which are more sensitive to the frequency respons

Low-power Auto Focus Algorithm Using Modified DCT for The Mobile Phones

Autor: Seung-Baek Park, Soon-Seob Lee, Yogendera Kumar, C.S. Kim, S.W. Kim

Publikováno v: 2006 Digest of Technical Papers International Conference on Consumer Electronics.

A new focus value calculation method based on the middle frequency component of DCT and applicable in auto focus function of a mobile phone is presented. Experimental results confirm the exactness in focus value calculation, power efficiency and immu

Swallow counterless DMP PLL

Autor: Soon-Seob Lee, Soo-Won Kim, Gwangseog Choi, Tae Geun Kim, Taewoo Kim

Publikováno v: ICVC '99. 6th International Conference on VLSI and CAD (Cat. No.99EX361).

This paper proposes a new simple architecture of digital dividing system in dual-modulus prescaler phase-locked loop for wireless communications. In this new architecture a swallow counter is not employed while the same total division ratio as in a c

High performance CMOS dual-modulus prescaler using selective latch technique

Autor: Tae Geun Kim, Soo-Won Kim, Soon-Seob Lee, Se-Yeob Kim

Publikováno v: ICVC '99. 6th International Conference on VLSI and CAD (Cat. No.99EX361).

This paper describes an improved CMOS dual-modulus prescaler (DMP) using selective latch technique for RF mobile communication systems. This technique enables high speed operation at reduced power consumption, which is obtained by reducing the number
