Increasingly powerful computers and the rapidly expanding use of picture processing and CAD/CAM systems in almost all industry branches have combined to generate a greater and greater demand for higher resolution graphic monitors. Controlling the video output stages of these graphic monitors is a key to producing such high resolutions. Until recently, only highly complex, expensive systems have be

Fiber optic transmission is assuming an increasingly important role in systems for wide-band analog signals and digital signals with high data rates. Although the number of applications for digital networks and telecommunications systems is skyrocketing, analog transmission is still vital to many applications. Analog systems with bandwidths of up to 150MHz are used for wide-band RGB signal distrib

With the increasing use of current-feedback amplifiers, the Diamond Structure has come to play a key role in today's analog circuit technology. Two new macro elements that function in this structure are the Diamond Transistor and its abridged version, the Diamond Buffer. These elements can be used for both voltage and current control of analog signals up to several 100MHz. The OPA660 combines both

Coax cables with a typical impedance of 50О© or 75О© are used in many applications to ensure signal fidelity, and high-speed line drivers have the often difficult job of transmitting signals over these cables or over twisted pair lines. The most common way to drive coax cables is to use driver amplifiers with low-impedance voltage output, which operate with either voltage or current feed

Have you ever had the experience of designing an analog gain block with an amplifier that is specified to be unity gain stable only to find that it is oscillating out of control in your circuit? Or have you ever replaced a stable voltage feedback amplifier with a current feedback amplifier to find that the current feedback amplifier immediately oscillates when placed in the amplifier socket? Oscil

This bulletin reflects the analysis power gained through knowledge of an op amp circuit's feedback factor. Feedback dictates the performance of an op amp both in function and in quality. The major specifications of the amplifier descibe an open-loop device awaiting feedback direction of the end circuit's function. Just how well the amplifier performs the function reflects through the feedback inte
