... A TIA pre-amplifier is used in RX to combine the benefits of voltage-mode (VM) and current-mode (CM) signaling. In VM, as the termination impedance decreases, the received voltage decreases and static current increases, but the bandwidth also increases [6], while in CM, both the signal current and b ...

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.
