Title: Laser diode driver
Inventor: EMA HIDETOSHI
IPC: G11B7/126
Filed: 1989-11-22
Abstract: PURPOSE:To perfrom high-speed operation by controlling a drive transistor or an electric field effect transistor for driving so that an emission instruction signal current and a photoelectric current become equal. CONSTITUTION:An emission instruction signal V0 that is inputted to the base of a transistor Q2 is converted into an emission instruction signal current, i.e. V0/R2, by a conversion means 2 and its conversion allows the emission instruction signal current to flow to the collector of the transistor Q2. Difference in electric currents between the emission instruction signal current in a conversion circuit 2 and a current source 3 is amplified by a field effect transistor Q4 and is impressed to the base of a drive transistor Q5. Then, the above impressed current allows a forward current to flow through the drive transistor Q5, a parallel circuits of a Zener diode D0 and a capacitor C0, and a resistance R0 thus emitting light. The resistance R0 detects the forward current and its current is converted into voltage and then the feedback of this voltage to the gate of the field effect transistor Q4 is performed through parallel circuit of a capacitor Cf and a resistance Rf.
