Two Active Elements Based All-Pass Section Suited for Current-Mode Cascading
A new circuit topology realizing a first-order currentmode all-pass filter is proposed using two dual-output second generation
current conveyor and two passive components. The circuit possesses low-input and high-output impedance, which makes it ideal
for current-mode systems. The proposed circuit is verified through PSPICE simulation results.
