IPC: G05F1/56
Filed: 1989-03-20
Abstract: PURPOSE:To detect accurately output current information without increasing the number of components nor exerting any influence upon a current limiting function by varying a reference voltage according to variation in the output voltage of a driving circuit for an output current. CONSTITUTION:This current detecting circuit is provided with a means 1 (reference voltage variation) which varies the reference voltage supplied to the uninverted input terminal of an operational amplifier 11 according to the variation in the output voltage of the driving circuit 13 for controlling the base of a power transistor (TR) 12. Namely, when a B-point voltage VB supplied by the driving circuit 13 is low level L, the specific reference voltage is applied to the uninverted input terminal of the operational amplifier 11 and when the voltage rises to high level H, the power TR 12 turns on to supply the output current. When the B-point voltage VB varies from L to H, the reference voltage varying means 1 detects that and varies the reference voltage according to the offset quantity and when the reference voltage varies from H to L, the reference voltage is varied to the specific reference voltage. Consequently, the current detection accuracy can be improved without exerting any influence upon the current limiting function.

Filed: 1989-03-20
Abstract: PURPOSE:To allow a driving circuit to cope with ultrahigh speed modulation or the like by detecting the fall of a pulse signal, forming a steep falling part to a bias current waveform and driving a laser diode. CONSTITUTION:When an inverted data signal is inputted to a flip-flop 10, a recessed pulse is outputted from an output terminal Q synchronously with the rise of the input signal (that is, the fall of an original data signal), the output from the output terminal Q is restored by the rise of the clock pulse inputted from a reset terminal R and a recessed single pulse with a narrow width is outputted and the bias current of a bias current output circuit 2 is lowered rapidly and restored to the original level. Consequently, the driving current of a laser diode 1 is lowered sharply and the current has a waveform, in which the level is lowered a little from the original bias current at the falling lower edge and then restored to the original bias current.
