Unformatted text preview: Page 1 of 4 EE 435 Homework 1 Spring 2012 Due Friday Jan 21 Problem 1 Identify one operational amplifier that has been published in one of the following in the past 5 years: IEEE Journal of Solid State Circuits IEEE Trans. On Cirucits and Systems (Part 1 or Part 2) IEEE International Symposium on Circuits and Systems Give the circuit schematic and briefly summarize the useful properties that the author claims for this circuit. Problem 2 Identify one operational amplifier that has been patented in the past 5 years. Give the circuit schematic and briefly summarize the useful properties that the author claims for this circuit. Problem 3 Consider the following operational amplifier. The goal is to obtain an expression for the small-signal output voltage in terms of the input variables V IN+ and V IN- . a) Write a complete set of small-signal equations that can be solved to obtain V OUT. Assume the small-signal parameter g o is present in all MOS devices....
