The proposed filter extends features of the previously presented Voltage Differencing Transconductance Amplifiers (VDTAs)-based frequency filter. It brings the new advantage of an electronic reconfiguration of its transfer. The proposed structure provides reconnection-less change between low-pass, band-pass, high-pass, band-stop and all-pass transfer functions. The electronic control of the filter parameters such as the pole frequency and quality factor remain preserved. The theoretical assumptions are supported by PSpice simulations using transistor-level models.
