Abstract:
1. A laser diode driver for coupling to a laser diode circuit, the laser diode circuit having a first laser diode circuit connection for coupling to a first power supply terminal, the first laser diode circuit connection being coupled to a first terminal of a first inductor, a second terminal of the first inductor being coupled to a first terminal of a laser diode and to a second laser diode circuit connection, a second terminal of the laser diode being coupled to a first terminal of a second inductor and to a third laser diode circuit connection, and a second terminal of the second inductor being coupled to a fourth laser diode circuit connection and through a first capacitor for coupling to a second power supply terminal; the laser diode driver comprising: a first current source including circuitry for controllably coupling a first current to the second laser diode circuit connection or to the fourth laser diode circuit connection responsive to an enable or bias input signal; a second current source including circuitry for controllably coupling a second current to the second laser diode circuit connection or to the third laser diode circuit connection responsive to a data input signal.
