In this study, a new triple output second-generation current conveyor (TO-CCII) based second-order current-mode (CM) universal filter is proposed. The proposed universal filter can simultaneously realize low-pass, band-pass, high-pass and notch filter responses. Moreover, it can provide all-pass responses with interconnection of notch and band-pass currents. One of the main advantages of the proposed universal filter is to include only grounded passive components which are advantageous from
integration point of view. It consists of a canonical number of capacitors, which is important for chip area. Also, it can provide high output impedance currents; accordingly, it can be easily connected with other CM structures. Frequency dependent nonideal
gain effects on the proposed filter performances are investigated. However, its input impedance is not low and a single resistive matching condition is required for the notch and all-pass responses. Simulation results based on 0.13 μm CMOS IBM technology parameters are given for the proposed universal filter through SPICE program. Power dissipation of the proposed universal filter is approximately found as 2 mW.
