In this paper time delay calculations for a current-mode circuit are considered and an equivalent circuit model for delay estimation is developed. The relation obtained for the time delay can be adapted to any CMOS current-mode circuit. The proposed calculation method is verified with SPICE using 0.35 mu m TSMC MOSIS technology parameters.Chamber Elect Engineers Bursa Branch; Istanbul Techn Univ, Fac Elect & Elect Engn; Uludag Univ, Dept Elect & Elect Engn; IEEE, Reg 8; IEEE Turkey Sect, CAS Chapter; Sci & Technol Res Council Turke
