Video Circuit Collection &mdash AN57
PDF, 559 Kb, 档案已发布: Jan 2, 1994
AN57, the Video Circuit Collection, features a variety of video circuits designed at LTC. The LT1204 70MHz multiplexer is featured in a number of circuits which require excellent video isolation from channel to channel. High speed voltage and current feedback amplifiers are highlighted throughout the section on video processing circuits. There is a section on applying Current Feedback Amplifiers (CFAs) and a number of articles taken from the Linear Technology magazine.

Application Note 57
January 1994
Video Circuit Collection
Jon Munson and Frank Cox
INTRODUCTION
Even in a time of rapidly advancing digital image processing, analog video signal processing still remains eminently
viable. The video A/D converters need a supply of properly
ampliп¬Ѓed, limited, DC restored, clamped, clipped, contoured, multiplexed, faded and п¬Ѓltered analog video before
they can accomplish anything. After the digital magic is
performed, there is usually more amplifying and п¬Ѓltering
to do as an adjunct to the D/A conversion process, not to mention all those pesky cables to drive. The analog way
is often the most expedient and efп¬Ѓcient, and you donвЂ™t
have to write all that code.
The foregoing is only partly in jest. The experienced engineer
will use whatever method will properly get the job done;
analog, digital or magic (more realistically, a combination
of all three). Presented here is a collection of analog video
circuits that have proven themselves useful. CIRCUIT INDEX

Operational Amplifier Selection Guide for
Optimum Noise Performance вЂ“ Design Note 140
Frank Cox
Eight years ago, George Erdi wrote a very useful Design
Note (DN6) that presented information to aid in the
selection of op amps for optimum noise performance,
in both graphical and tabular form. Design Note 140 is
an update of DN6. It covers new low noise op amps as
well as some high speed op amps. Although a great deal
has changed in eight years, especially in electronics,
noise is still a critical issue in op amp circuit design
and the LTВ®1028 is still the lowest noise op amp for
low source impedance applications.
The amount of noise an op amp circuit will produce
is determined by the device used, the total resistance
in the circuit, the bandwidth of the measurement, the
temperature of the circuit and the gain of the circuit. A
convenient п¬Ѓgure of merit for the noise performance
of an op amp is the spectral density or spot noise. This
is obtained by normalizing the measurement to a unit
of bandwidth. Here the unit is 1Hz and the noise is reported as вЂњnV/в€љHz.вЂќ The noise in a particular application
bandwidth can be calculated by multiplying the spot
noise by the square root of the application bandwidth. …

A Broadband Random Noise Generator вЂ“ Design Note 70
Jim Williams
Filter, audio and RF communication testing often requires a random noise source. The circuit in Figure 1
provides an RMS amplitude regulated noise source with
selectable bandwidth. The RMS output is 300mV with
a 1kHz to 5MHz bandwidth selected in decade ranges. output feeds LT1228 A4, a current feedback ampliп¬Ѓer.
A4вЂ™s output, the circuitвЂ™s output, is sampled by the A5
based gain control conп¬Ѓguration. This closes a gain
control loop back at A3. A3вЂ™s ISET input current controls
its gain, allowing overall output level control. The A1 ampliп¬Ѓer, biased from the LTВ®1004 reference,
provides optimum drive for D1, the noise source. AC
coupled A2 takes a broadband gain of 100. The A2
output feeds a gain control stage via a simple selectable
lowpass п¬Ѓlter. The п¬ЃlterвЂ™s output is applied to LT1228
A3, an operational transconductance ampliп¬Ѓer. A3вЂ™s To adjust this circuit, place the п¬Ѓlter in the 1kHz position
and trim the 5k potentiometer for maximum negative
bias at A3, Pin 5.
