Abstract: | The current paper presents a novel Schmitt trigger using two second‐generation current conveyors and four resistors and its application as a relaxation oscillator. The performance of the proposed circuit is examined using Cadence and the model parameters of a 0.6µm CMOS process. The obtained results demonstrate excellent agreement with the theoretical values. The measured results based on commercially available current feedback operational amplifiers (AD 844 AN) are included and the non‐idealities are also examined. The topology reports low sensitivities and has features suitable for VLSI implementation. Copyright © 2010 John Wiley & Sons, Ltd. |
