Odd-and even-order electronically controlled wave active filter employing differential difference trans-conductance amplifier (DDTA)

P Rana, A Ranjan - International Journal of Electronics, 2021 - Taylor & Francis
In recent years, several current mode wave active filters have been reported in literature.
However, most schemes only have a few higher-order filters that employ a wave-equivalent …
