A. A VCO consists of a tank circuit and a positive feedback amplifier. For offset frequencies greater than the VCO's half bandwidth, fo/2QL, the phase noise has no positive feedback and is determined only by the ratio of the oscillator signal level and thermal amplifier noise. If we ass...
We plan on using the OPA3S2859 as for several reasons: · It offers low input impedance to the ADS1285 · Running both Sample and Reference through a single die will minimize noise. · Its selectable gain should help in spanning the dynamic range. I have a few questions: · Have ...
There are many ways to reduce the distortion of power amplifiers, such as using high-quality electronic components, rationally designing circuits, increasing negative feedback, and so on. In addition, using high-quality audio cables and speakers can also effectively reduce distortion. How to choose ...
Figure 16. Multiple AD5253/AD5254 Devices on a Single Bus. In wireless base station smart antenna systems that require arrays of digital potentiometers to bias the power amplifiers, large numbers of AD5253/AD5254 devices can be addressed by using extra decoders, switches, and input/output buse...
Our recommended enclosure size is based on an actual test enclosure with our amplifiers. To achieve the same excursion in larger enclosures, one should really use smaller amps. The consequence of not doing so is the driver can be pushed beyond the mechanical excursion limit. On the other hand...

multiple feedback options, isolation, and other features available on analog platforms today. When digital servo amplifiers, came about in the late 1900's, even more features such as position control, network communication, digital input/output, and pre-programmed moves became possible. With more ...

Q: What are current feedback amplifiers? A: Current feedback amplifiers are op amps that feed back a portion of the output signal as current in order to control the amplifier. Current feedback amplifiers differ from voltage feedback amplifiers that rely on feedback in the form of a voltage...
