摘要：
In this paper, a new two-input three-output second-order universal filter is proposed. Two multi-output voltage controlled current followers (MO-VCCFs) and two capacitors are used in the proposed filter. The proposed filter does not have external passive resistors. It has high output impedances yielding easy cascadability. It has the property of electronic tunability. It does not need any critical passive component matching conditions. Also, it is composed of only grounded capacitors; accordingly, it is suitable for integration. Theoretical knowledge is supported via SPICE simulations.
