Inventor: KURIHARA TAKASHI
IPC: H03F3/34
Filed: 1999-12-13
Abstract: PROBLEM TO BE SOLVED: To suppress output current leakage when an input voltage Vin is 0 V and also to improve the linearity of voltage/current conversion. SOLUTION: A PNP transistor Q3, an NPN transistor Q4 and a current source I2 are defined as pairs with respect to a PNP transistor Q1, an NPN transistor Q2 and a current source I1 respectively. The current values of the sources I1 and I2 are made equal. Current caused to flow to the transistors Q2 and Q1 are made equal to current caused to flow to the transistors Q4 and Q3. Thus, voltages between the bases and emitters of the transistors Q1 and Q3 become equal, and voltages between the bases and emitters of the transistors Q2 and Q4 become equal. Then, the detection voltage Vin becomes equal to voltage applied to both ends of a resistance R with high accuracy. The voltage Vin is subjected to current conversion by the resistance R where the voltage coinciding with the voltage Vin with high accuracy is applied to the both ends and is outputted as an output current Iout from an output end 7 through an NPN transistor Q5.

Abstract: PROBLEM TO BE SOLVED: To solve problems in which incoming turbulent light such as solar rays impinges on the side of an infrared photodetector used in a free space optical communication device to deteriorate the photodetector in an S/N ratio, signal light incident on the light receiving surface of the photodetector does not impinge on a semiconductor chip which photoelectrically converts light into electric signals but passes through its side to deteriorate the photodetector in an S/N ratio, furthermore an infrared photodetector becomes expensive because a visible light cutting resin is used as a part of a case to shut off a visible light incident on the light receiving surface of the infrared photodetector, and the infrared photodetector gets low in degree of freedom of design because the above resin is smoky. SOLUTION: A light shielding member is arranged on the side of a infrared photodetector to shut off incoming turbulent light. The inner surface of the light shielding member is subjected to a reflection treatment to increase signal light. Furthermore, a visible light cutting member is arranged on the light receiving surface of the infrared photodetector, by which expensive visible light cutting resin can be lessened in usage, and the infrared photodetector can be markedly improved in degree of freedom of design.

Title: Apc circuit
Inventor: MORISHITA YASUNARI
IPC: H03G3/20
Filed: 1992-12-18
Abstract: PURPOSE:To prevent spurious radiation from being caused when the transmission state is switched to the reception state by controlling a connected circuit with a switch circuit so as to decrease or make the gain of a power amplifier circuit zero by means of a switch circuit when a transmission power supply voltage is a prescribed voltage or below. CONSTITUTION:The transmission state is switched to the reception state by setting a prescribed voltage at which a transistor(TR) Q3 is nonconductive slightly lower than a normal voltage of a transmission power supply voltage VCC and when the transmission power supply voltage VCC is decreased, the TRQ3 is immediately nonconductive. A TRQ1 is nonconductive regardless of an output of a comparator circuit 22 by the nonconduction of the TRQ3. Then a TRQ2 is nonconductive and a voltage of a collector is low because no voltage is given thereto and the gain of a power amplifier circuit 16 is made zero. As a result, the spurious radiation to a vicinity channel is not caused just after the transmission state is switched to the reception state.
