摘要： A laser diode driving circuit capable of providing a suitable output current to a laser diode is disclosed. The laser diode driving circuit includes a current supply, a first pseudo laser diode, a second pseudo laser diode, and an output current mirror circuit. An input current provided by the current supply is output through the output current mirror circuit to the laser diode. By making the characteristic of each of the first and second pseudo laser diodes substantially equal to the characteristic of the laser diode, the non-linearity between the input current and the output current is compensated.

摘要： An engine control system in which control of an engine can be performed after there has been a momentary power disconnection of a power supply, such as the vechicle battery, from an engine control unit of an electronic circuit which executes an anti-theft function. A power supply detecting circuit detect a connecting of the power supply to the engine control unit. A further circuit determines on the basis of the vehicle speed and the RPM whether or not the vehicle is running. When a connecting of the power supply to the engine control unit is dectected, a determination is made whether or not the power supply connecting has occured after a preceding momentary power disconnection if the further circuit determines that the vehicle is running. The anit-theft function of the electronic circuit is disable when it is determined that there has been a preceding momentary power desconnection.
