ELE 489/562 Biomedical Instrumentation Exam #1 Spring 2009 Name: Open book/note. 10 points for each question (10 x 10 = 100 points). 1. As shown on the right, six parameters of an ideal operational amplifier are listed. Circle the correct value for each parameter. 2. ( ) Refer to the circuit on the right for questions 2 to 5. The stage-1 gain is defined by (V 3- V 4 ) / (V 1- V 2 ). If we want to set the first-stage gain to 5.7, what value should be chosen for R 1 ? (A) 100 K Ω , (B) 200 K Ω , (C) 330 K Ω , (D) 470 K Ω , (E) none of the above. 3. ( ) The stage-2 gain is defined by V 5 / (V 3 – V 4 ). What is the gain for stage 2? (A) – 4.7, (B) –5.7, (C) –9.4, (D) –11.4, (E) none of the above. 4. ( ) Stage 3 is a bandpass filter with a passing band between 1 Hz and 30 Hz. If we choose C 5 = 2 μ F, what value should R 5 be set at? (A) 24 K Ω , (B) 33 K Ω , (C) 56 K Ω , (D) 80 K Ω , (E) none of the above. 5.
