New Solution of a Frequency Filter with Reconnection-less Reconfiguration of Its Transfer
This contribution provides a novel solution of a reconnection-less reconfigurable filter based on voltage differencing transconductance amplifiers (VDTAs) and variable gain amplifier (VGA). The structure offers the 2nd-order functions of all pass, band stop, low pass, low pass with transfer zero alongside with the 1st-order high-pass function and direct transfer in dependence on setting of DC voltages. The electronic control of pole frequency and quality factor of the filter is provided. Furthermore, the filter can change its pole frequency while maintaining bandwidth constant. Simulations in Cadence IC6 (spectre) software were performed to verify the design.
