This paper presents an electronically tunable current-mode first-order universal filter. The proposed circuit employs only a single Extra-X Current-Controlled Conveyor (EX-CCCII) and a single grounded capacitor, which is suitable for IC implementation. The circuit can realize three current transfer functions simultaneously, namely low-pass, high-pass and all-pass. The proposed circuit exhibits low-input and high-output impedance, which is suitable for cascading. The pole frequency of the filter can be electronically tuned, by varying the bias current of EX-CCCII. The nonidealities and parasitic effects on the circuit performance are investigated in detail. Also, the Monte Carlo analysis is done to show the effect of active and passive element mismatches on the pole frequency. An eight-phase current-mode sinusoidal oscillator and current-mode second-order filter are further realized using the proposed circuit. The functionality of the proposed circuits is verified through PSPICE simulations, using 0.25-[Formula: see text]m TSMC CMOS technology parameters.

Simulation Results

Two new configurations realizing canonical first-order current-mode all-pass sections (APSs) using a single third generation current conveyor (CCIII) are given. Using each configuration, two types of first-order all-pass filters can be derived giving rise to four distinct circuits for APS, three of which are novel. Each APS employs only a single CCIII and a minimum of passive components: one resistor and one capacitor. The circuits are suited for MOS implementation. The SPICE simulation results for frequency response as well as transient response are incorporated to verify the theory.
