Abstract

A novel structure, based on balanced differential-pair, is proposed to implement the CMOS CCCII with negative intrinsic resistance at port X. HSPICE simulations, based on the AMS´s 0.35mu CMOS process, are conducted, which certainly confirm the occurrence of negative resistance. To demonstrate its capability, a two-phase current-mode oscillator is synthesized based on two lossless integrators. As little error in oscillated frequency is observed, the proposed structure earns its place as one of the attractive negative-resistance simulators.
