Abstract
PURPOSE: To stably execute an operation without reducing the degree of amplification, by connecting 2 signal sources by a negative impedance transducer so that one signal source becomes a load for converting the negative impedance to the other source.
CONSTITUTION: 2 signal sources 30, 40 showing an approximate quality in case when they are regarded as a load are connected by a negative impedance transducer 45, the signal source 30 is made a load for converting the negatve impedance to the signal source 40, and the signal source 40 is made a load for converting the negative impedance to the signal source 30. Subsequently, signal source impedance values 38, 48, and line impedance values 39, 49 are denoted as ZR1, ZR2, and ZL1, ZL2, respectively, and in case of ZR1+ZL1=Z1, ZR2+ZL2= Z2, and Z1-Z2ΔZ, the degrees of power amplification α, β from the left side to the right side and from the right side to the left side become α=ZR2/ΔZ and β=ZR1/ΔZ, respectively, Z1 appreximates Z2, and the smaller ΔZ becomes, the larger degree of amplification is obtained.
