Filed: 1993-07-23
Abstract: PURPOSE:To perform an integration equalization and a partial response PR (-1, 0, 1) equalization with a common equalization circuit by inventing an equalization circuit. CONSTITUTION:The terminal of a delay line DL is shorted with an imaginary shorting by being connected to the inversion input terminal of an OP amplifier IC2 and the delay line DL is driven by the signal source of the characteristic impedance Z0 being equal to the Z0 of the DL. Then, a current output signal flowing through the shorted terminal of the delay line DL becomes to be a signal delaied by the delaying time of the delay line. Further. when the voltage signal input of the delay line DL is taken-out from an OP amplifier IC1, the signal becomes to be a signal equalized by the PR (-1, 0, 1) system equalization. Thus, a circuit can be used in common with the integration equalization and the PR (-1, 0, 1) equalization since the difference between delaied quantities of the equalized signal and the current output signal is not generated as a principle.

Filed: 1990-07-31
Abstract: PURPOSE:To form the new buffer circuit of a fixed distortion by cascading a first and a second emitter follower transistors whose conductive forms are different, and allowing a current proportional to the base current of the transistor of an output side to make it flow to the transistor of an input side. CONSTITUTION:To a third NPN transistor Q3, the same current as that of a second NPN transistor Q2 is made to flow. Accordingly the base current of Q3 is equal to the base current of Q2. Accordingly, from the output of a current mirror circuit C, a current of double of the base current of Q2 flows, and this current is divided and flows to the base of Q2 and the emitter of a first PNP transistor Q1. Therefore, a current being equal to the base current of Q2 flows to Q1. Subsequently, as for the relation of an input voltage VIN and an output voltage VOUT, as shown in the expression, the output voltage VOUT is shifted by a prescribed voltage against the input voltage VIN. This shifted magnitude is constant irrespective of the input voltage VIN. In the expression, K:T:(g):Isg1, Isg2:hFEQ2: and VBEQ1, VBEQ2 denote a Boltzmann's constant, an absolute temperature, charge of an electron, saturation currents of Q1, Q2, a current amplification factor of Q2, and base-emitter voltages of Q1, Q2, respectively.
