WIDE RANGE BAND PASS FILTER
DESCRIPTION:
Third-Order Wideband Bandpass Filter
This circuit demonstrates the operation and characteristics of a wideband bandpass filter, constructed by cascading a second-order low-pass and a high-pass filter. As a result, a 300 Hz to 3 kHz bandpass voice filter is formed.
Experiments:
Set the function generator to 1 kHz and the oscilloscope's time base to 0.2 ms/DIV. Increase the input frequency, about 1 kHz at a time up to 4 kHz, constantl ....etc

I am Manzil Duarah a B.E final year student. My seminar topic for my final semester is A very linear low pass filter with automatic frequency tuning. I don't have the necessary documents for making the seminar report. So i wanted the full text document on this topic. So i would be very thankful if you help me out.
The abstract of the topic is as follows :

Abstract

An integrated photonic microwave bandpass filter has been demonstrated incorporating a coherently coupled microring resonator in low-loss polymers. The resonator was designed to have an extremely small bandwidth so that it could be used to selectively pass the optical signal carrying the microwave signal to attain efficient bandpass filtering. The demonstrated device may feature compact size, simple structure, stable operation, possible tuning via the thermooptic effect, and furthermore flexible integration with other electrical/opt ....etc

A Low-Light CMOS Contact Imager With an Emission Filter for Biosensing Applications
In the article is described a fully functional low light 128 128
contact image sensor for cell detection in biosensing applications. 0.18micrometer CMOS technology is used to fabricate it. It has a low-noise operation by employing both a modified version
of the active reset (AR) technique. for
fluorescence imaging, we need High-sensitivity and low noise performance. These attributes are inegrated into this sensor. an emission filter is specially fab ....etc
