Quasi-passive filter for harmonic filtering
Electric Power Systems Research, 2008To overcome the limitations of conventional shunt passive filters, a quasi-passive filter has been proposed in this paper. It comprises of a parallel and series tuned LC tank circuit. Unlike the conventional shunt passive filter, the quasi-passive filter utilizes a large value ac capacitor.

A critical study of various types of passive notch filters is made. The distributed parameter notch filters are found to be superior in performance as compared to the lumped RC and lumped-distributed types. The frequency response curves indicate that tapering in distributed notch filters improves the notch selectivity.

Novel passive recursive CCD bandpass filters have been realized using standard two-level-polysilicon gate NMOS technology. A Chebyshev bandpass (w/SUB rel,/ /SUB 3/ /SUB dB/=3.1 percent) and a fully integrated CCD signal filter with an extremely narrow 3 dB bandwidth of 97 Hz (Q=1350) at 131.85 kHz center frequency were implemented by means of cascaded

Multi-output passive digital filters
2004 IEEE Electro/Information Technology Conference, 2004In this paper, a new family of four multi-output second-order passive digital filters constructed from four passive digital two-ports are presented. The conditions for passivity in a passive digital two-port are first defined. Four passive two-ports are introduced, their passivity and stability constraints on coefficients, and pseudopower expressions ...
