3 all parts please will give like!!!

1 a) Design a noninverting amplifier with a gain of 100 using ideal op amps and practical values of resistors. Draw a schematic of your circuit showing input, output, and all resistor values. b) If the op amp in part la) is not ideal but has an input offset voltage of +/- 5mV and input bias currents of 100nA and the source resistance at the input is 50k ohms, then what is the range of the output voltage when the input is zero volts? Show and explain our calculations. 2 a) Calculate the output voltage in the circuit below using superposition. Assume that the op amps are ideal and that Va-50mV and Vb-30mV. b) What is common mode rejection ratio (CMRR) and why is it important? c) If the circuit below has 80dB of CMRR and there is IV of common mode signal, then how much of the common mode signal will be present at the output? 20K ak LOK 3. Find the output voltage v, in each of the 3 circuits below and explain how you found it. Assume all op amps are ideal. No IDK 100ml 10K3 100, jok 10 ml 10k 20k www 20k MELONE N₂ 10K 20-V d. Draw the circuit diagram for the 3 op amp instrumentation amplifier and show appropriate values for all the resistors so that the amplification of differential signals is 100. e. What is the primary advantage of this configuration and what is required of the resistors in order to achieve this benefic? Why is this benefit essential to the practical problem of amplifying real transducer signals? f. If the input voltage is set to zero in the circuit of b, what is the maximum range of the output voltage if the input offset voltage maximum value is +/- 8mV and the input bias current maximum is 200 nanoamps?
