1) A digital to analog convertor provides an output from 0 to 5V.Design an operational operational amplifier circuit that maps theunipolar voltage output to a bipolar output that varies from -5V to5V. Using a LMH6619, design the circuit, perform SPICE simulationand present results in graphical form.
2) An input signal consists of asmall AC component and a large DC offset. The DC offset can bebetween 0 and 5V. The AC amplitude is on the order of 100 to200 mV. Based on LMH6619, design a circuit that will subtracta DC value and amplify the remaining signal by 100, and places theoutput on a 2.5V DC offset. Design the circuit, perform aSPICE simulation and present results in graphicalform.
