Patent JP-H0451605-A (JP)
Title: Solid power amplifier device
Inventor: SHIINO SO
IPC: H03F3/193
Filed: 1990-06-19
Abstract: PURPOSE:To efficiently obtain a high output signal where higher harmonics are removed by substituting a low pass filter removing higher harmonic components for a notch filter and using a parallel gap capacitor for removing the drain bias component of high output GaAsFET. CONSTITUTION:The parallel gap capacitor 12 with less passing loss and the notch filter 13 are used for removing the higher harmonic components. The drain bias component of an RF signal is removed at the same time as when the parallel gap capacitor 12 composed of parallel two wires of a 1/4 line length in a passing signal wavelength attenuates the higher harmonics. The higher harmonics of the RF signal is furthermore attenuated in the notch filter 13 composed of a 50OMEGAline preventing the secondary higher harmonics band and plural overn stubs. Thus, the loss of the output circuit of high output GaAsFET 6 and power consumption are reduced and the power efficiency of a device is improved.

Title: Stabilization system for photosensor
Inventor: IMAMURA TOMOATSU
IPC: H01L33/00
Filed: 1984-07-31
Abstract: PURPOSE:To simplify a circuit by connecting a resistance in series with a light emitting element and controlling the voltage across the light emitting element and resistance to a constant level. CONSTITUTION:The anode of an LED5 is connected to a power source +V through a transistor (TR) 105 and a resistance 106 and the cathode of the LED5 is grounded through a resistance 107. An operational amplifier 103 is a circuit which controls the base current of the TR105 through a resistance 104. Then, the terminal voltage VF across the LED5 and resistance 107 is held constant and then when the temperature rises, a drop in VF due to the temperature rise is compensated by increasing the current, so that the temperature dependency of the output of a photodiode is reduced. In this case, the output temperature characteristic of a photodetection diode when the LED current is constant is smaller than the LED current temperature characteristics when VF is constant, so the photo-diode output tends to increase slightly according to the rise in temperature. For the purpose, the resistance 107 is connected in series with the LED5 to reduce a current increase, stabilizing the photodiode output.
