OPTICAL SENSOR SYSTEM INCLUDING SERIES CONNECTED LIGHT EMITTING DIODES |
摘要 |
A current source circuit to drive a light source in an optical sensor system is disclosed. The current source includes an inductor connected in series with a resistor, and a diode coupled in parallel with the inductor and resistor. The current source is configured to receive a regulated direct current (DC) voltage and to provide the current through the inductor to the light source when a switch is closed, and to divert current through the inductor to the diode when the switch is open. |
