Liebe tt gemeinde

Nein, leider kann ich betreffend dem mbrk projekt nichts neues berichten. Die arbeiten haben über ein jahr nun geruht, nachdem wir uns im vergangenen jahr uns ein altes bauernhaus gekauft hattten, ein halbes jahr auf baustelle gelebt hatte und überall noch lange die umzugskisten nicht ausgeräumt waren. Mittlerweile ist der umbau abgeschlossen, fürs erste auf jeden fall. Platz für die nächste amp nabellschau ist reichlich vorhanden.

Mit dem mbrk projekt werde ich bald wieder anfangen, nachdem ich die amp küche wieder eingerichtet habe. Das soll bald sein!

Bis bald und herzliche grüsse euch allen - ein untoter meldet sich zurück

An operational amplifier is one of the most versatile and important units in an analog-to-digital conversion circuit. Fully differential op amps are op amps that have both input and output differential signals. Compared with ordinary single-ended output op amps, they have the following advantages: The output voltage swing is large; better suppression of common mode noise; Low noise; even order terms that suppress harmonic distortion are better. Therefore, high performance op amps are often used in fully differential form. In recent years, the higher unity gain bandwidth of the fully differential op amp and the larger output swing make it more widely used in high speed and low voltage circuits. With the increasing data conversion rate, high-speed analog-to-digital converters are becoming more and more demanding, and high-speed analog-to-digital converters require high gain and high unity gain bandwidth op amps to meet system accuracy and rapid setup requirements. Speed ​​and accuracy are the two most important performance indicators of analog circuits. However, the requirements of the two are mutually restrictive and contradictory. Therefore, it is difficult to meet both requirements at the same time. The folded cascode technology can solve this problem more successfully. The op amp of this structure has a high open loop gain and a high unity gain bandwidth. The disadvantage of the fully differential op amp is that the common mode loop gain of the external feedback loop is small, and the output common mode level cannot be accurately determined. Therefore, a common mode feedback circuit is generally required.
