CCII-Based Nth-Order Mixed Mode Elliptic Filter with Grounded R and C

Abstract

This paper presents a new nth-order elliptic filter structure with second generation current conveyor (CCII). Synthesis methodology for mixed mode odd and even order filter is proposed. The designed structure is emphasized on the basis of implementation of integrated circuit fabrication by using grounded passive components (resistors and capacitors). The proposed structure is designed for different point of interests: (i) no component constraint, (ii) the structure is compatible with equal capacitance design, which is suitable for integrated circuit fabrication, (iii) low sensitivity like LC ladder filter and (iv) nearly null group sensitivity. To validate the theory, HSPICE simulation with 0.13-μm process and BSIM level 53 model is carried with ±1.5 V power supply.
