R1=100k, R2-100k, Rz-1k, VZ-5.6 , RL=1k, VDDzSv, VSS--Sv IE-0.1mA, Beta-infinity a. Find VL b. Find Zout c. Find the output offset voltage (Le ground the positive input of the opal and calculate VL d. If the input devices o1 and O2 are changed to bipolar devices with a beta of 100, find the output offset voltage e. How can you modify the opamp to improve the common mode rejection? Draw the resulting opamp
