Abstract

A new design for a class AB second generation current conveyor implemented from bipolar transistors is proposed to considerably decrease the parasitic series resistance R_X. SPICE simulation results, using the nominal parameters for the transistors of the 2 μm HF2CMOS technology from SGS THOMSON, are given, with ±2.5-V supplies and I₀= 300 μA, the values of R_X are 1.3 n for the proposed CCII against 53 Ω for the conventional one, as an application example, a voltage mode bandpass filter with Q=90 at f ₀=150 MHz has been implemented from the new conveyor and two surface mounted passive components only
