Southeast University Bangladesh Department of EEE Fall 2021 Midterm Assignment Course: EEE 225/2201/2043, Electronics II Questions: 1. The op-amp in the circuit is ideal, except for non-zero input bias currents. Further, R1 -10K and R2 = 30K. What should R3's value be? R2 (а) 10K (b) R1 + R2 = 30K (с) 0 (d) R1||R2 = 7.5K 2. Design a circuit using op-amp which will perform the following, Vo=m(E1-E2), value of m=YZ, where YZ being the last two digits of your SEU ID 3. In the circuit below, the op-amp is ideal, except for an input bias current |Ib| = 1 nA. urther, RF = 1OK, R1 = 100 Q and C = 0.1 µF. The switch is opened at t = 0. What is the output voltage after 5 seconds? RF R1 Vo Switch * Tip: For t> 0, the voltage across the capacitor is v;= vc = (+IþAt)/C_ |4. In the circuit VREF = 2.5 V, and VIN = 1.5 V. The output voltage is
