In Proceedings of the 2003 10th IEEE International Conference on Electronics, Circuits and Systems, 2003. ICECS 2003. 1, (pp. 276-279). http://dx.doi.org/10.1109/ICECS.2003.1302030
In this paper, a new realisation of DVCC based current mode all-pass filter circuit is proposed. This circuit employs only one active element and three passive elements of which two are grounded. Using the proposed filter topology a new quadrature oscillator is presented as an application. SPICE simulations verify the theoretical results.
