B In Figure 1 B On Page 3 The Empirical Junction Diode Equation Is Vp Nvt In Ip Is For Diodes Di D2 D3 And 1 (44.38 KiB) Viewed 21 times
(b) In Figure 1(b) on.page 3, the empirical junction diode equation is: Vp= nVT In [Ip/ Is] = for diodes Di, D2, D3 and D4 where n= 1, Vt.= 26 mV at room temperature, Is = 5 x10-17 A, the resistors Ri= R2 = R4 = 30 k2.; R3 = Rs = 15 k 2 and the DC voltage source Vs=8 V Find the DC quiescent operating point or. Q-point (ID; VD) of the diodes Di, D2, D3 and Dä (to 3 decimal places in uA and V, respectively). Note: The diodes are all identical where Vpi = VD2 = VD3 = VD4 and Idi = ID2 = ID3 = 104. (10 Marks)
