Correct option is D
Infinite offset voltage is not a characteristic of an ideal operational amplifier (op-amp). An ideal op-amp has zero offset voltage, meaning that the output voltage is zero when both inputs are at the same voltage.
Explanation
·
Infinite input impedance
An ideal op-amp has infinite input impedance, which means that the input source sees an infinite impedance.
·
Infinite bandwidth
An ideal op-amp has infinite bandwidth, which means that it has a completely flat gain magnitude from dc to any frequency.
·
Infinite open loop gain
An ideal op-amp has infinite open loop gain, which means that it has infinite gain.
·
Zero output impedance
An ideal op-amp has zero output impedance, which means that it has an ideal source.
·
Zero offset voltage
An ideal op-amp has zero offset voltage, which means that the output voltage is zero when both inputs are at the same voltage.
