4 Quick evision on JT Fixed iasing JT 1-4
5 Load Line Analysis The end points of the load line are: sat = / = 0 cutoff = = 0 ma The Q-point is the operating point that sets the values of and at certain value JT 1-5
6 ircuit alues Affect the Q-Point JT 1-6
7 ircuit alues Affect the Q-Point JT 1-7
8 ircuit alues Affect the Q-Point JT 1-8

10 Solution JT 1-10
11 mitter-stabilized ias ircuit Adding a resistor ( ) to the emitter circuit The addition of the emitter resistor to the dc bias of the JT provides improved stability the dc bias currents and voltages remain closer to where they were set by the circuit when outside conditions (e.g., temperature) change JT 1-11

14 xample (2) A bipolar junction transistor having S = A is biased in the forward active region with =750 m. f the current gain (or β) varies from 50 to 200 due to manufacturing variations, calculate the minimum and maximum terminal currents of the device. JT 1-14
15 Solution For a given, the collector current remains independent of β The base current varies from /200 to /50: the emitter current experiences only a small variation because (β+ 1)/β is near unity for large β: JT 1-15
16 oltage Divider ias ircuit This is a very stable bias circuit. The currents and voltages are nearly independent of any variations in. JT 1-16

18 Problem Design the bias circuit shown in the figure for the silicon npn JT such that = 1mA, 1 =22k Ω and 2 =2.2kΩ, if the transistor has β equals 100. JT 1-18
19 D ias with oltage Feedback ircuit Another way to improve the stability of a bias circuit is to add a feedback path from collector to base n this bias circuit the Q-point is only slightly dependent on the transistor beta, JT 1-19
20 D ias with oltage Feedback ircuit ase-mitter Loop From Kirchhoff s voltage law: 0 Where << : ' Knowing = and, the loop equation becomes: 0 Solving for : ( ) Then / ( ) JT 1-20
