Given two NMOS FETs having (kn'/2)(W/L) = (3 KW)^-1 and Vt = 3V. Using a single 10V dc power supply, design a differential pair amplifier having 1mA bias current in each transistor. What is its maximum gain for linear operation (balanced input, balanced output)? Assume ro = 8.Hint: Increase the value of RD until the MOSFETs leave their saturation regions.
A DC circuit consists of a battery and a coil (not a resistor). The coil has a resistance of R = 5W and an inductance of L = 100mH. At a particular instant in time after a battery is connected across the coil, the current is i = 2.0 A
