Question

Problem (2): PAGE: # All PN junctions shown below have a voltage drop of 0.6V when they are “Forward Biased". Assume R_id = (NX.Nz) k22, Indicate in the table whether the diodes Du. Dis and D2 are Forward/Reverse with the given VA and Vs. Also give the corresponding Vous numerical values. +4V DAR_id D VOUT R_id D18 -2V Problem 2 Schematic VA VR Di Mode Die Mode D2 Mode Vout (sign and numerical value) OV OV OV +4 V +4 V +4 V
