  • Digitally-programmable switched-current filters

    Creator:
    Yesilyurt, Ayse Gul
    Abstract:
    Digitally-programmable filters have been an ongoing research topic for a number of years. The first such filters were FIR transversal filters using Charge-Coupled Devices (CCD's) and IIR recursive filters using switched-capacitor (SC) techniques. Although both techniques achieve excellent results, they require non-standard and/or additional IC fabrication steps. Low substrate doping...

  • High accuracy CMOS switched-current ladder filters

    Hoei, Jung-sheng
    Abstract:
    Clock-feedthrough effects, channel-length modulation and device mismatch are the main causes of the inaccuracy of Switched-Current (SI) circuits. In this paper, these non-ideal effects are analyzed. A high-performance current mirror, namely regulated cascode current mirror, which eliminates drain voltage variation problem is introduced. By using this current mirror as a...
