What is an operational transconductance amplifier? Operational transconductance amplifiers (OTAs) have become essential building blocks of many modern analog and mixed signal circuits. OTAs are used ...

The very basics of operational amplifiers. Learn comparator, inverting, and non-inverting op-amp configurations. An operational amplifier, or op amp, is a dc-coupled high-gain electronic voltage ...

In operational amplifier stability, one rule of thumb is to allow 45 degrees of phase margin. Other design guidelines state that 60 degrees is best; still others say that 30 degrees is sufficient.
