MT-056: High Speed Voltage Feedback Op Amps
ثبت نشده
چکیده
In order to intelligently select the correct high speed op amp for a given application, an understanding of the various op amp topologies as well as the tradeoffs between them is required. The two most widely used topologies are voltage feedback (VFB) and current feedback (CFB). An overview of these topologies has been presented in previous tutorials (MT-050, MT051, MT-052), but the following discussion treats the frequency-related aspects of the two topologies in considerably more detail.

Voltage Feedback ( Vfb ) Op Amp Designed on an " All Npn " Ic Process
High speed analog signal processing applications, such as video and communications, require op amps which have wide bandwidth, fast settling time, low distortion and noise, high output current, good DC performance, and operate at low supply voltages. These devices are widely used as gain blocks, cable drivers, ADC pre-amps, current-to-voltage converters, etc. Achieving higher bandwidths for les...
متن کاملAnalysis and Design of Active-r Oscillators Using the Current-feedback Op-amp
A systematic approach has been employed to synthesize sinusoidal active-R oscillators using the current feedback op-amps. This approach is an extension to the method employed in [1] for the design of active-R oscillators using voltage op-amp. It is found that the active-R technique applied to current-feedback op-amps will be suitable for high frequency oscillator circuits with high output ampli...

The OPA643 provides a level of speed and dynamic range previously unattainable in a monolithic op amp. Using a de-compensated voltage feedback architecture with two internal gain stages, the OPA643 achieves exceptionally low harmonic distortion over a wide frequency range. The "classic" differential input provides all the familiar benefits of precision op amps, such as bias current cancellation...

Transimpedance or current feedback amplifiers are still relatively new to audio applications, since they are pri marily designed for video circuits. While the AD846 (an early high-per formance example) was successfully used in TAA,1 transimpedance amps may not be completely familiar de vices (The AD846 data sheet contains a detailed discussion of transimped ance amplifier theory). Interesti...
متن کاملHigh Speed Op-amp Design: Compensation and Topologies for Two and Three Stage Designs
As CMOS technology continues to evolve, the supply voltages are decreasing while at the same time the transistor threshold voltages are remaining relatively constant. Making matters worse, the inherent gain available from the nano-CMOS transistors is dropping. Traditional techniques for achieving high gain by vertically stacking (i.e. cascoding) transistors becomes less useful in sub-100nm proc...
