Problem 2.104

An op amp is connected in a closed loop with gain of +100 utilizing a feedback resistor of 1 M. (a) If the input bias current is 100 nA, what output voltage results with the input grounded? (b) If the input offset voltage is 1 mV and the input bias current as in (a), what is the largest possible output that can be observed with the input grounded? (c) If bias-current compensation is used, what is the value of the required resistor? If the offset current is no more than one-tenth the bias current, what is the resulting output offset voltage (due to offset current alone)? (d) With bias-current compensation as in (c) in place what is the largest dc voltage at the output due to the combined effect of offset voltage and offset current?

ECE 3301 Homework Assignment 1 1. The current flowing past a point in a device is shown in the given figure, where A = 15. Calculate the total charge through the point. The current entering the positive terminal of a device is i(t) = 9 e mA and the voltage across the device is v(t) = 7 V. 2. Find the charge delivered to the device between t = 0 and t = 2 s. 3. Calculate the power absorbed by the device. 4. Determine the energy absorbed in 3 s. 5. Consider the network given below, where I = 11 A and I = 5 2. Calculate the power absorbed by each element in the given network. 6. A 1­kW toaster takes roughly 4 minutes to heat four slices of bread. Find the cost
