Phase-synchroniser based ongm-Call-pass filter chain with sliding mode control

The paper presents a general structure for realizing current-mode (CM) fractional-order all-pass filters (FOAPFs) using generalized first-kind five-port current conveyors (GCC5s). The proposed circuit topology employs two GCC5s and minimum number of passive components, i.e.. one resistor and one fractional-order capacitor, both in grounded form. A total of eight CM FOAPFs using second-generation current conveyor are derived, which are capable of providing simultaneously both inverting and non-inverting current-outputs from high impedance terminals. A theoretical study of a variant created using universal current conveyor is provided, which verify the concept of the proposed circuit topology.

This paper considers design procedure of fast locking time self-tuning [Formula: see text] biquadratic band-pass filter with nonlinear sliding mode control. A sliding mode controller is building block of the phase control loop (PCL) involved to push central frequency to reach input signal frequency very fast, approximately 100–200[Formula: see text]ns. The sliding mode controller is realized by using a tunable delay line, enabling optimal filter locking time for different input signal frequencies. The filter possesses low sensitivity to component discrepancy and is applied as a selective amplifier. The 0.13[Formula: see text][Formula: see text]m SiGe BiCMOS technology has been utilized for design and verification of the presented filter. This filter has central frequency up to 220[Formula: see text]MHz, quality factor [Formula: see text] and 25[Formula: see text]dB gain.
