Document Summary
Instructions: the points allocated to each problem on this exam are as indicated. All work should be included on the exam itself. Attach additional sheets only if you run out of space on a problem. Students may bring 1 page of notes to the exam. Calculators are permitted but can not be shared. As an alternative, the signal could be amplified by putting this small signal to the input of a transconductance amplifier. The transconductance amplifier output could then serve as an input to a transresistance amplifier. By alternately cascading transconductance and transresistance amplifiers with appropriate gains, a large voltage gain could be obtained. If the transconductance and transresistance amplifiers are nonideal (that is, the input and output impedances are not ideal), the nonideal input and output impedances problem can be overcome by placing buffers between the stages. The required input and output impedance characteristics of these buffers would be different than that of the voltage buffers discussed in class.
