A dc current of 26 μA flows through the circuit shown. The diode in the circuit is forward biased and it has an ideality factor of one. At the quiescent point, the diode has a junction capacitance of 0.5 nF. Its neutral region resistances can be neglected. Assume that the room temperature thermal equivalent voltage is 26 mV.
For ω=2×106 rad/s, the amplitude of the small-signal component of diode current (in μA, correct to one decimal place) is
Correct : 6.4
