Novel first order all-pass sections using a single CCIII

Two novel first order voltage-mode all-pass sections using a single third g eneration current conveyor (CCIII) are given. In addition the first circuit uses three resistors and one capacitor and the second circuit which is der ived from the first circuit uses two resistors and one capacitor. A current -mode first order all-pass section requiring one capacitor and one resistor is also proposed. SPICE simulation results are incorporated to verify the theory.
