The IC differential amplifier is to be fabricated in a CMOS technology having the technology specifications of Kn' = 200 uA/V. Kp' = 100 uA/V. Vtn = 1V Vtp = -1V Va = 50V L = 1u. Calculate all the device widths for a constant bias current of 1mA for the differential pair and a voltage gain Vo/Vin of 100. Calculate the value of R. Indicate the function of each transistor anf calculate the output resistance at differential output terminals.
