Title: Differential amplifier circuit
Inventor: KOGA HIROSHI
IPC: H03F3/34
Filed: 1990-10-30
Abstract: PURPOSE:To suppress the fluctuation of an input offset voltage dependent on an early voltage by balancing each load in a differential input circuit corresponding to a pair of input voltage through the feed back work of an output voltage. CONSTITUTION:Corresponding to a power source voltage VDD and a grounded potential VSS, and input terminals 51 and 52 and an output terminal 53, the circuit is constructed to provide PNP transistors 1-5, NPN transistors 6-9, a diode 10, and a current source 11. Since nodes 101 and 102 are clamped at the almost same potential, a current difference due to an Eearly's effect in the collector current of the PNP transistors 2 and 4 becomes an almost same current value. In general, the respective collector current and differential current of the PNP transistor 4 and the NPN transistor 9 are outputted, and even the small change of the input voltage is taken out as a big current change, and can be outputted through the output terminal 53.

Filed: 1987-11-24
Abstract: PURPOSE:To miniaturize each electrode for a semiconductor laser array element by supporting a plurality of leads for inputting a signal by an insulator base body, arranging the end sections of these leads in response to respective electrode in a plurality of laser-beam outgoing regions and joining the end sections with these electrodes. CONSTITUTION:Leads in the same number as electrodes for a semiconductor laser array element 11 are disposed in parallel at the same intervals, and monolithic-molded into a flexible filmy insulator base body, thus manufacturing a lead 13. These lead electrodes 17 are joined with the electrodes for the element 1 through thermocompression bonding by using solder. Pawls 15 are fitted into pawl holes 18 shaped to a photo-receptor base 16, and the lead 13 is fixed. Consequently, since the lead 13 has flexibility, the areas of the electrodes 17 can be designed in size approximately the same as those of the electrodes for the joined element 11 even when there is a stepped section between an electrode section for the array element 11 and the photo-receptor base 16, thus efficiently dissipating the heat generation of the array element 13. A positional displacement margin, etc., at the time of wire bonding need not be considered at all, thus allowing miniaturization.
