Abstract

A new voltage-mode (VM) multifunctional filter using only two voltage followers (VFs), two resistors and two capacitors is proposed. The proposed filter with two inputs and two outputs can provide low-pass (LP) and high-pass (HP) responses. It does not need any critical passive component matching constraints. Additionally, it has low output impedances, low power dissipation and adequately low THD values. However, it does not have high input impedances; accordingly, it requires an extra VF to obtain high input impedance. A number of time domain and frequency domain simulations and experimental tests are performed to verify the claimed theory.
