Single FDCCII-based mixed-mode biquad filter with eight outputs
AEU - International Journal of Electronics and Communications, 2009Abstract The transconductance and the transresistance modes might act as the bridge transferring from voltage-mode to current-mode and vice versa, respectively. A novel mixed-mode (including voltage, current, transconductance, and transresistance modes) biquad filter with one input and seven outputs or two inputs and eight outputs is presented.

Multifunction mixed-mode filter using FTFNs
Analog Integrated Circuits and Signal Processing, 2006A novel mixed-mode multifunction filter configuration containing three FTFNs and only five passive components with a single input and three different outputs is presented. The configuration can be driven by a voltage or current source while as outputs are always voltages and currents.

A new mixed-mode filter based on MDDCCs
SPIE Proceedings, 2015A new mixed mode filter based on MDDCC (Modify Differential Difference Current Conveyor) is proposed, the structure of filter is simple, the circuit consist of only three active MDDCCs, five resistors and three grounded capacitors. The filter can realize the filter of current mode and voltage mode, which can realize the function of low pass biquad ...

Mixed Mode Filters (Short Papers)
IEEE Transactions on Microwave Theory and Techniques, 1974Mixed mode bandpass filters are described which utilize alternating TE/sub 011//spl deg/ and TE/sub n11//spl deg/ circular waveguide cavity modes. This novel filter configuration exhibits both excellent unloaded Q and spurious mode response characteristics.
