The most direct way to compensate a current feedback op amp to drive a capacitive load is the addition of an "out of loop" series resistor at the amplifier output as in method 2. Part Number Ch BW MHz SR V/ms vn nV/ Hz in fA/ Hz VOS mV Ib nA Supply Voltage Range [V] IQ mA...
Slowly increase the amplitude of the input signal to 2 V still centered on 2.5 V and export the waveforms into your lab notebook. The output voltage of any op amp is ultimately limited by the supply voltages, and in many cases the actual limits are much smaller than the supply voltages d...
View the Functional Block Diagram of an NE5534 op-amp Q1, Which output is class-A? Q2, Which input is that of the VAS (voltage amplifier stage)? Q3, How would you change the open-loop gain? TheGmof an op-amp differential input stage is that low that the voltage amplifier stage does...
The circuit may be changed to function as a non-inverting adder by switching the connections to the op-amp's inverting and non-inverting inputs, as illustrated in the figure below. The output equation could be made simpler by assuming that all of the input resistors have identical values. ...

However, when Riis sufficiently large compared with Rs(Ri=∞), the first term of the equation can be approximated to 1, and viewed as Vs=Vi. Regarding the second term, the amplified input voltage AvViis divided and output based on the opamp output resistance Roand load resistance RL. ...
Note: Because the output current of the op amp is unknown at 1) and 2), it is not possible to list the KCL equation or node voltage equation at the output of the op amp. In addition, the op amp output uo in 2) should be treated as an independent voltage source. ...
