摘要：

In continuation to the recently proposed catalogue of second-order CFOA-based explicit-current-output (ECO) oscillators by Gupta et al., this paper reports CFOA-based ECO oscillators using only two CFOAs and grounded capacitors. Nine oscillator circuits are reported here and depending on the governing tuning laws, they are classified under three different types. Experimental results using AD844 CFOA ICs have validated the workability of the proposed circuit. (C) 2010 Elsevier GmbH. All rights reserved.
