University of California, Berkeley Fall 2010 EE 42/100 Prof. A. Niknejad Problem Set 5 [revA - 10/6/10] Due Friday (5pm), October 15, 2010 1kΩ 4kΩ 1MΩ 1MΩ 1kΩ v d 1 v d 2 v c 1. A sensitive measurement is made using the above amplifier. Two small signals v d 1 = 10 μ V cos ω 1 t and v d 2 = - 8 μ V cos ω 1 t appear in the presence of a strong common-mode signal v c = 155 mV cos ω 2 t . (a) Find the output signal and the signal-to-common-mode ratio. (b) Repeat the calculation but now assume that due to manufacturing tolerances, the component values only match within 1%. Use the worst case mismatch. C 1 C 2 C 3 C 4 C 5 C 6 C 7 C 8 C 9 2. Using the ‘+’ and ‘ || ’ operators, find the equivalent capacitance of the above network. Note that || is an operator, x || y = xy/ ( x + y ), and does not indicate topology.

(c) What is the net energy? 2 C 1 v s v o R 2 R 1 R 3 R 3 R 2 R 2 5. (a) Find the transfer function of the above circuit. (b) Calculate the output signal when the circuit is excited by a periodic square wave signal input signal shown below. The period of the signal is 1 μ s and the rise and fall times are 10% of the period. C 1 = 9 . 7nF, R 1 = 15kΩ, R 2 = 130kΩ, and R 3 = 570Ω. v ( t ) 1V t ( μ s) 1 6. Suppose you want to store enough energy in a capacitor so that you can run your 1kW microwave oven for 30 minutes. How big is the required capacitance if you can charge it up to 100V? What are the capacitor dimensions if you build it as a parallel plate square capacitor with a dielectric with relative permittivity ǫ r = 10 with a thickness of 1 μ m. 3...
