3.2.9Bandpass filter – narrow Anactive filterwith a twin–T network as the feedback element Sign in to download full-size image When twin-T is used as the feedback element, ZTis very high at the centre frequency ωoand thus the gain of the active op-amp circuit is a maximum. At ...
This paper describes the design strategy and implementation of a high frequency low voltage pseudo-differential SC filter which use opamps with gain enhancement replica amplifier. Experimental results of a biquad SC bandpass with a center frequency of 10 MHz and a Q of 10 are presented. The real...

The designed peak gain of the filter sets the minimum open-loop gain requirement of the op-amp for proper functioning. Two ICs were used in testing the filters: uA741 and TL071. The f_(unity) of the uA741 is 1 MHz, the less noisy TL071 is markedly better with 5MHz f_(unity) (...
The author discusses basic design issues such as Q reduction, noise enhancement, op-amp settling, and power consumption associated with MHz-range switched-capacitor bandpass filters. Experimental results are presented for a sixth-order, all-pole, differential CMOS bandpass filter which has a center ...
The selectable lowpass/bandpass filter IC Is a CMOS chip that can be configured for either a lowpass or a bandpass filter. The lowpass response can be a 7 pole Butterworth, Elliptic or Bessel filter. The band pass response can be a six pole full, third or sixth octave bandpass filter....
Polarization independent integrated filter based on a cross-slot waveguide. We investigate an in-line band pass filter, working both for TE and TM polarizations, based on a cross-slot waveguide merged with a Bragg grating and an op... Matthieu,Roussey,Petri,... - 《Optics Express》 被引量...
A switched-capacitor (SC) bandpass interpolating filter is proposed with the capability of achieving, simultaneously, channel selection and frequency up-translation, together with sampling rate increase, in a multirate configuration at high frequency. This filter has been designed for efficient use in ...
