    • A CMOS 100 MHz continuous-time seventh order 0.05° equiripple linear phase leapfrog multiple loop feedback Gm-C filter 

      Su, H.W.; Sun, Y. (Institute of Electrical and Electronics Engineers (IEEE), 2002)
      A novel 100 MHz CMOS Gm-C seventh-order 0.05° equiripple linear phase low-pass multiple loop feedback (MLF) filter based on leapfrog (LF) topology is presented. The filter is implemented using a fully-differential linear, ...

    • Performance comparison of continuous-time IFLF and LF low-pass all-pole OTA-C filters 

      Su, H.W.; Sun, Y. (Institute of Electrical and Electronics Engineers (IEEE), 2000)
      This paper presents the performance comparison of two typical multiple loop feedback all-pole operational transconductance amplifier-capacitor (OTA-C) filters: inverse-follow-the-leader-feedback (IFLF) and leapfrog (LF) ...

    • Ring Structure and Warp of NGC 5907: Interaction with Dwarf Galaxies 

      Shang, Z.; Zheng, Z.; Brinks, E.; Chen, J.; Burstein, D.; Su, H.W.; Byun, Y.; Deng, L.; Deng, Z.; Fan, X.; Jiang, Z.; Li, Y.; Lin, W.; Ma, F.; Sun, W.; Wills, B.; Windhorst, R.A.; Wu, H.; Xia, X.; Xu, W.; Xue, S.; Yan, H.; Zhou, X.; Zhu, J.; Zou, Z. (1998)
      The edge-on, nearby spiral galaxy NGC 5907 has long been used as the prototype of a “noninteracting” warped galaxy. We report here the discovery of two interactions with companion dwarf galaxies that substantially change ...

    • Single-amplifier integrator-based low power CMOS filter for video frequency applications 

      Hill, C.; Sun, Y.; Su, H.W. (Institute of Electrical and Electronics Engineers (IEEE), 2002)
      This paper describes a new low power fully differential second-order continuous-time low pass filter for use at video frequencies. The filter uses a single active device in combination with MOSFET resistors and grounded ...

    • Tuning of continuous-time filters using genetic algorithms 

      Sun, Y.; Chan, B.T.; Su, H.W. (Institute of Electrical and Electronics Engineers (IEEE), 2000)
      A tuning method of continuous-time filters is proposed which is based on genetic algorithms. Simulation results show that the method can be used to tune OTA-C filters for a given accuracy within a reasonable time.
