Abstract: PURPOSE:To attain the impedance matching by eliminating the adverse effect due to a length of a line of a negative feedback circuit by inserting a resistor among an input terminal, an output terminal of a high frequency amplifier element and the negative feedback circuit and connecting both the resistors in the middle of the negative feedback circuit with a capacitor. CONSTITUTION:A resistor R1 is connected between an input terminal 2 of a high frequency amplifier element 1 and one terminal of a negative feedback circuit 4 and a resistor R2 is connected between an output terminal 3 of the element 1 and the circuit 4. Then a capacitor C giving a feedback capacitance is inserted in the middle of the negative feedback circuit 4, the negative feedback circuit 4 and a main microstrip line are connected by the resistors R1, R2 and the main microstrip line is not directly connected to the capacitor C. In order to increase the gain of power, the resistance of the resistor R2 is to be much higher, but the resistance of the resistor R1 is to be decreased, and then the power gain is moved in the decreasing gain. Thus, the relation of R1=R2 is to be set to obtain a stable amplifier while keeping a high gain.

Abstract: PURPOSE:To generate a digital signal with less misreading of data by providing a time adjusting means to reduce the timewise overlap of an analog signal and binary signal each other. CONSTITUTION:A low source voltage Vd generated from a common source voltage Vcc which is applied via a common power source line, through a resistor R and zener diode Z, is applied to the power source terminal of an amplifier 2'. For this amplifier 2', the one having the characteristic such that the delay amount (time) through the amplifier 2' becomes large, is used since the process time becomes slow when the source voltage Vd becomes low. Then, by means of lowering the source voltage Vd than the common source voltage Vcc, the delay amount is made to increase, for instance, then the delay time adjusting means to reduce the overlap of the analog signal and binary signal generating an obstructive signal is provided to make the error rate lower. By this procedure, the analog signal and binary signal become not to be timewise overlapped each other, therefore, the error generation rate of binary signal due to the interference signal can be lowered.
