LMH High Speed Op Amps

Which answer does not hold true for both current feedback and voltage feedback?
Infinite non-inverting input impedance
Output voltage source is zero
Infinite inverting input impedance
All of the above

What happens if the feedback resistor value is increased for a CFA?
Gain increases
Bandwidth reduces
Output offset increases
All of the above

What kind of amplifier should be used when trying to get high output swings in differential line drivers?
Parallel Amplifier
Single ended Amplifier
Bridge Amplifier
None of the above

NEXT (Near end cross talk) distortion can happen in both the upstream and downstream side. It is vital to have the extremely low distortion characteristics on which side so it does not carry over to another side?
Transmit Side
Receiving Side
Either Side
Low distortion doesn't matter
