Document Summary

Total points: 100: this is a closed book exam. However, you are allowed to bring two page (8. 5 x 11 ), single-sided notes: no electronic devices, i. e. calculators, cell phones, computers, etc, show all the steps on the exam, remember to put down units. Points will be taken off for answers without units. Uc berkeley: (22 pts) assume the diode in the circuit below using the simple piecewise model with a threshold voltage of 0. 6v (also known as the large signal model in the text book). Vo (i) (4 pts) re-draw the circuit assuming the diode is off. V0=2v1=2vin/3 (1pts) (1pts) (4 pts) re-draw the circuit assuming the diode is on. Vin -0. 9v (2pts) (iv) (4 pts) plot vo vs. vin. 0. 9v, -0. 6v, positive side slope and shape (each 1pts) (v) (6 pts) now suppose vin = 3 sin(2 t). Plot vo versus time for 0 < t < 2s. 2v, -0. 6v, clamping on reverse side each are 2 pts.
