can you help me this problem

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 +/- 5m V 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=50m V 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 2k 40K M + 1 iOK 2k 40
