Op-ampgainfeedbacklatch-upphase-marginA power-efficient, voltage gain enhancement technique for op-amps has been described. The proposed technique is robust against Process, Voltage and Temperature (PVT) variations. It exploits a positive feedback-based gain enhancement technique without any latch-up...
Current feedback op amps traditionally have wider bandwidths and higher slew rates than voltage feedback amplifiers and feature constant bandwidth which is independent of gain. A current feedback op amp responds to an error current at its low-impedance negative input terminal, rather than an erro...

The operational amplifier (op amp) circuit configuration uses a high-gain amplifier whose parameters are determined by external feedback components. The amplifier gain is so high that without these external feedback components, the slightest input signal would saturate the amplifier output. The op amp...
As it approaches 100%, the op amp approaches instability. If possible, keep it well away from this limit. Also notice that this graph is for a specified gain. For a voltage feedback op amp, capacitive load drive capability increases proportionally with gain. So aVF op amp that can safely...
op amp. The inverting input terminal is connected in feedback to one end of the resistor R1and the source of transistorM1. The output of the op-amp drives the Gate of the transistor. The high open loop gain of the amplifier will force the Gate ofM1to the required voltage such thatVIN...
Where VOUTis the voltage at the output terminal of the op-amp. ACLis the closed loop gain. The feedback circuit connected to the op-amp determines the closed loop gain ACL. VD= (V1– V2) is the differential input voltage. We say the feedback as positive if the feedback path feeds ...

Gain-bandwidth product: The forward gain, G is defined as the gain of the op-amp when a signal is fed differentially into the amplifier with no negative feedback applied. This gain is ideally infinite at all frequencies, but in a real op-amp is finite, and depends on the frequency. At...
