Name one linear AC Op Amp limitation.
|
Finite Bandwidth (small signal effect)
|
|
|
Name one non-linear AC Op Amp limitation.
|
Slew Rate distortion
|
|
|
What do input bias current, input offset current and input offset voltage cause to happen to the output?
|
Causes an offset on the output.
|
|
|
What shape is the output signal due to slew rate distortion?
|
Triangle wave
|
|
|
Give the formula for calculating the Full Power Frequency of an amplifier.
|
Fsr = SR/(2*pi*Vout)
Vout = peak voltage |
|
|
What is the typical Slew Rate for a 741 Op Amp?
|
0.5v/uS
|
|
|
Define the relationship between Unity Gain freq (Ft), Open Loop Gain (Aol), and the open loop break frequency (Fbol).
|
Ft = Aol * Fbol
|
|
|
Define the relationship between Unity Gain freq (Ft), Closed Loop Gain (Acl), and the Closed loop break frequency (Fbcl).
|
Ft = Acl * Fbcl
|
|
|
What is another name for the Full-Power Bandwidth of an op amp?
|
Slew Rate Limiting Freq
|
|
|
How can you eliminate or reduce the effect of bias current at the input terminals of an Op Amp?
|
Add a bias compensating resistor equivalent to Rf||Rin
|
|
|
How do you calculate the closed loop bandwidth of an inverting opamp?
|
Ft / (|A| + 1)
|
|
|
