difference between op amp and other amplifiers OTA is a TRANSCONDUCTANCE amplifier which means that it's GAIN is given by Io/Vin=A (For a certain Voltage input you will have an output current Io which will be A times Vin). This means that the output current is independent of your load ...
Using the proposed transconductor, an op amp and a differential difference amplifier (DDA) were implemented in a 1.2-/spl mu/m CMOS process. The transconductor has a total harmonic distortion (THD) of less than -60 dB for an input swing of 400 mV at 10 kHz. The op amp and the DDA...
I really wouldn't sweat making the choice too much. Heck, I don't usually care what chip an amp uses. Unless the design of an amplifier is messed up or is intentionally coloured, it's likely to sound quite similar to most other a...

Furthermore, most discrete op-amp circuits have poor common-mode rejection and an input voltage range smaller than the power supply voltage. While have better common-mode rejection, they still suffer from gain drift due to the inherent mismatch between on-chip devices and the external gain ...

The term Op-Amp oroperational amplifieris basically a voltage amplifying device. It uses exterior feedbackcomponentsbetween its inputs as well as output terminals like resistors & capacitors. An ideal operational amplifier has different characteristics which include the gain of open-loop is infinite, ...
well is more a receiver (radio + built-in amp) which requires external speakers. A receiver conclude a tuner and power amplifier? But many AV receivers don't have tuners. So a AV receiver is not a traditional receiver? OP Kimbrough Xu Active Member Joined May 18, 2022 Messages 289 ...
