Classification: CPC H  G | IPC H

Claim 0:
1. A pulsed laser diode driver comprising:
a refresh circuit configured to receive a DC input voltage and to generate a refresh current using the DC input voltage, wherein a current amplitude of the refresh current is controlled by the refresh circuit based on a voltage level of a source voltage received by the refresh circuit;
a first source capacitor having i) a first terminal directly electrically connected to the refresh circuit to receive the refresh current and to develop the source voltage therefrom, and ii) a second terminal electrically coupled to ground;
a first inductor having a first terminal that is directly electrically connected to the first terminal of the first source capacitor; and
one or more switches configured to control a current flow through the first inductor to produce a high-current pulse through a first laser diode, the high-current pulse corresponding to a peak current of a resonant waveform developed at an anode of the first laser diode.
