... Now you will design the bandgap circuit shown above to generate VREF = 1.2V. We will set R3 = R2. Your op-amp may be a simple differential pair or a two stage opamp. It needs to run off of VBAT because at this point you don’t have any other voltages to work from. The bipolar PNP transistors ar ...

Stepper motor
A stepper motor or step motor or stepping motor is a brushless DC electric motor that divides a full rotation into a number of equal steps. The motor's position can then be commanded to move and hold at one of these steps without any feedback sensor (an open-loop controller), as long as the motor is carefully sized to the application in respect to torque and speed.Switched reluctance motors are very large stepping motors with a reduced pole count, and generally are closed-loop commutated.
