摘要

In this short paper, we propose new voltage- and current- controlled negative impedance converter (NIC) circuits based on two operational amplifiers in a positive and negative feedback configuration. The proposed circuits have a wider linear range than the classical single and dual op amp NICs and better frequency response. Simulations and experimental results are presented to confirm the theoretical analysis.
