Single Active Element based Current-Mode All-Pass Filter

In this paper, a current-mode all-pass filter employing single multi-output dual-X second-generation current conveyor, a grounded resistor and a grounded capacitor is proposed. The circuit is as good as ideal for current-mode cascading by possessing low input and high output impedances. The use of grounded passive components makes the circuit, ideal for IC implementation. The effect of non-idea...

Delayless Harmonic Filter for Single Phase Inverter Using Neural-Network

This paper presents about the feedforward neural networks for various waveform processing and delayless filtering that are applicable to power electronics.
