Integrated mixed-mode digital-analog filter converters
IEEE Journal of Solid-State Circuits, 1990Alternative architectures have been investigated for the integrated realization of DAFICs (digital-analog filter converters), taking into account such important design parameters as capacitance spread and total capacitor area, conversion speed and resolution, and the hardware complexity of the analog and digital parts. To demonstrate the feasibility of

Mixed-mode universal filter using OTAs
2012 IEEE International Conference on Cyber Technology in Automation, Control, and Intelligent Systems (CYBER), 2012This paper presents an electronically tunable versatile biquadratic filter. Unlike the typical voltage-mode and current-mode filter, the proposed filter can realize voltage-mode, current-mode, transconductance-mode and transresistance-mode transfer functions without changing the circuit topology, called a mixed-mode filter.

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 Novel Mixed-Mode OTA-C Filter
Frequenz, 2003A novel mixed-mode biquad circuit is presented. The circuit uses six single-output- and one dual-output-operational transconductance amplifiers, two grounded capacitors; and can realize lowpass, highpass, bandpass, notch, lowpass-notch, highpass-notch and allpass responses from the same topology.

CFOA‐based simple mixed‐mode first‐order universal filter configurations
International Journal of Circuit Theory and Applications, 2022AbstractThis brief communication presents two current feedback op‐amp (CFOA)‐based simple first‐order mixed‐mode universal filter topologies—one of them providing first‐order low‐pass (LP), high pass (HP), and all pass (AP)—all the three filters in voltage‐mode (VM)/trans‐admittance‐mode (TAM) while the other one realizing the quoted three functions in

Mixed modes dielectric resonator loaded cavity filters
1994 IEEE MTT-S International Microwave Symposium Digest (Cat. No.94CH3389-4), 2002A novel configuration of dielectric loaded cavity filters is presented. The new filter combines the superior spurious free performance of TE/sub 01/ mode ring dielectric resonators with the advantage of HE/sub 11/ dual-mode dielectric loading. Resonant frequency and field distributions of each cavity is computed by rigorous mode-matching technique. The
