EE Laboratory Assignment 9 The BJT Differential Amplifier by Dr. A.V. Radun Dr. K.D. Donohue (3/27/07) Department of Electrical and Computer Engineering University of Kentucky Lexington, KY Simulation-only Lab # 9 Due at Next lecture period I. Instructional Objectives Simulate a simple differential amplifier in SPICE. 11 Differential Amplifier Circuits - - and Vout2 = 2 V V out (d) out (c) − () Let A V1 = V out1 /V in1 be the gain of differential amplifier due to input V in1 only and A V2 V out2/V in2 due to input V in2 only. Then from superposition theorem, the output voltage V out is equal to V out = A V1 Vin1 + A V2 www.doorway.ru substituting V in1 and V in2 from equation () and (), the. An op amp differential amplifier can be created by combining both a noninverting voltage amplifier and an inverting voltage amplifier in a single stage. Proper gain matching between the two paths is essential to maximize the common-mode rejection ratio. Differential gain Author: James M. Fiore.

4 differential amplifier using bjt 15 5 darlington amplifier using bjt 18 6 source follower with bootstrapped circuit 21 7 class - a power amplifier 24 8 class – b complementary symmetry power amplifier 27 9 frequency response of ce amplifier with emitter resistance amplifier 32 10 dc response of cs amplifier Electronics II Lab EELE Page 1 of 8 Experiments #6 Differential Amplifier 1) Objectives: To understand the DC and AC operation of a differential amplifier. To measure DC voltages and currents in differential amplifier. eq 1: Differential amplifier output expression in the general case Differential mode. The configuration R 1 ≠R 2 ≠R f ≠R g is however never used in real circuits. What we should aim for when designing a differential amplifier is to get an output of the form V out =A(V 2-V 1), with A being a common factor.
