EE310 lab 9 Abstract. In this lab today we are going to be doing Door 1 which is essentially messing around with Input voltages and seeing how amplifiers are affected when using a potentiometer to o... ffset input voltage and whatnot. Data Analysis. Fig1. Above are all 3 Circuits and their respective equation relating to Vo relating to Door #1 First we build the ckt 1 all the way to the left via the eqn (1 + ???? ) * ??? = ?0(?? = 100?), (?? = 100) We have 3 givens Rfactual = 98.1K Riactual = 100.2 & Vo=.343 here we don't have a potentiometer involved thus we can use our givens to solve for Vos seen below ? ?? = ? ? (1+ ?? ?? ) → 0. 00034 Now we have a potentiometer involved to eliminate offset meaning vo is now 11.04 so we solve again for Vos ? ?? = ? ? (1+ ?? ?? ) → 0. 01126 2. For the next circuit we want to solve for Ib1 and we do this by using the second circuit in Fig1. Vo=.064 Ractual=.99M ??1 = ?? ? → .064 .99? = 6. 3636364? - 11 3. We do the same for circuit 3 as we did for Ckt 2 vo=.033 ??2 = ?? ? → .033 .99? = 3. 3333333? - 11 Fig2. This figure Represent Ckt 2 with a input Offset using a potentiometer and the Multimeter reads are Vo voltage received which is equal to -0.002593 Now we use the same formula as in ckt 2 and compare the responses of multisim and our experiment.
