None 2p2i221Some applications (e.g., differential amplifiers or cascode amplifiers) require current sources with avery high output resistance. One of the methods for achieving this goal is by using the principle ofcascoding. The figure shows a double-cascode current source, which is used to generate some biascurrent I for the circuit above it. The transistors Q1-Q3 are identical and have the same bias point.Determine (approximately) the value of the small-signal resistance of this current source, Tout, seenlooking into the drain of Q3, as indicated in the figure.VDDCircuitVBIAS3 Q3VBIAS2Q2VBIAS1 Q1ToutI = 0.2 mAVov = 0.1 VVA = 1.5 VTout 15 kbTout 22.5 ks?Tout 30 kn4Tout 225 kTout 2.7 MS-Tout 5.4 MgTout 7 MRh Tout 13 MQ
