Title: Current amplification ratio compensation circuit
Inventor: CHIGIRA HIROKAZU
IPC: H03F1/30
Filed: 1992-08-18
Abstract: PURPOSE:To automatically compensate output current even if a current amplification ratio fluctuates by setting current flowing in the collector/emitter path of a transistor where the output terminal of a negative feedback amplifier is set to a base to be constant. CONSTITUTION:The negative feedback amplifier 9 is constituted by transistors 10 and 11 which are differentially connected, transistors 12 and 13 which are current mirror-connected, an output transistor for feedback/buffer 14 and a resistance 15. The base voltage of the transistor 10 and than of 11 always become equal by the negative feedback operation of the amplifier 9. When the current amplification ratio of the transistors 6 and 11 deteriorate, the base current of the transistor 11 increases, the voltage of an output terminal 17 rises by that quantity and the base current of the transistor 6 increases. Base current is that generated in accordance with the fluctuation of the current amplification ratio, and the fluctuation amounts of the current amplification ratios of the transistors 6 and 11 are almost equal when base current is generated by same IC. Thus, current becomes compensation current against the transistor 6.

Title: Waveform equalizing circuit
Inventor: OGAWA TAKUJI
IPC: G11B5/09
Filed: 1985-10-02
Abstract: PURPOSE:To obtain the signals having small spread and no undershoot by adding the waveform of an attenuation signal shift to both plus and minus sides by the same time to a basic waveform and changing these added waveforms into an optional waveform by a waveform processing circuit having a transmission function for addition. CONSTITUTION:An input signal waveform 3 is branched to a partial delay line 9a and an attenuator 15a. The waveform passed through the line 9a is divided into a part reaching a delay line 9b and the other reaching an adder 7. A terminal resistance 10 is provided at the output of the line 9b and therefore the signal passed through the line 9b is applied to an attenuator 15b. When the signal passed through the line 9a is defined as a basic signal, the output signals of both attenuators 15a and 15b are shifted by +tau and -tau respectively in terms of time and also the amplitude of both signals are small compared with the basic signal. Here the waveform processing circuits 8a and 8b having special transmission functions are provided at the output sides of both attenuators 15a and 15b respectively. Thus an appropriate transmission function is set and a desired waveform is obtained.
