Beschreibung
Zusammenfassung:	In some implementations, an electrical drive circuit may generate a rectangular optical pulse using cathode pre-charge and cathode-pull compensation. The electrical drive circuit may include an anode and a cathode to connect an optical load, a switch, a first source connected between the anode and a ground, a rectifier connected between the cathode and the switch, a capacitor connected in parallel with the rectifier, a second source connected to the ground, and an inductor connected between the switch and the second source. In some implementations, when the switch is closed and the optical load is connected, a first current is provided to the optical load through the first source, the rectifier, and the switch, and a second current is provided to the optical load through the first source, the capacitor, and the switch, where a rise time of the first current complements a fall time of the second current.
