Step 8.025P Refer circuit diagram Fig the textbook Draw the small signal equivalent circuit for the + + + - - Figure Step At current Write the formula for trans conductance Substitute 10: for and 25 10-3 for V, Step 14 Write the formula input resistance Substitute 100 for and for 8. 100 Step 14 Write the formula for output resistance Substitute 10 for and for 10 MQ Step Write formula gain. Substitute for 8m and 1x 10-3 V/V Step At current Write the formula for trans-conductance Substitute for and 25 for 8m =4 mA/V Step Write the formula for input resistance Substitute 100 for and for 8. 100 Step 14 Write formula output resistance V. Substitute 10 for and 100 x for 10 =0.1MQ Step Write formula gain Substitute mA/V for and 0. for 400 V/V Step 10 of 14 At current Substitute and 25 10-3 for V. =40 mA/V Step 11 of 14 Write formula for input resistance Substitute 100 for B and 40 10-3 for 100 Step 12 of 14 Write output resistance c Substitute 10 for and 1000 for 10 =0.01MQ Step 13 of 14 Write formula gain Substitute for g. and 0.01x for V/V Step 14 of 14 Thus, the values small signal parameters and A, collector currents 100 and are listed table & (in A/V) (in (in MQ) (in V/V) 10 0.4 250 1 400 100 4 25 0.1 400 1000 40 2.5 0.01 400
