Özet
A novel voltage mode first order all-pass filter configuration is proposed. The presented circuit uses a single fully differential current feedback operational amplifier (FDCFOA), resistors and a grounded capacitor. High input impedance of the proposed filter enables the circuit to be cascaded without additional buffers.It does not impose any component matching constraint in analog signal processing circuits. Moreover higher order all-pass filter could be achieved by cascading the proposed all-pass sections.In order to demostrate the performance of the proposed filter a new voltage mode oscillator is introduced as an application example. Also the theoretical results are verified with SPICE simulations using a CMOS realization of FDCFOA.
