    摘要： An integrator circuit (10) receiving a current signal from the anode terminal of a photodiode (PD) includes a two-input, two-output fall-differential amplifier (A0), capacitors (C01, C02), switches (S01, S02, S11, S12), and an additional capacitor (Ca). The capacitor (C01) and the switch (S01) are connected in parallel between the negative and positive input terminals of the full-differential amplifier (A0). The negative input terminal of the full-differential amplifier (A0) is connected with the anode terminal of the photodiode (PD). The capacitor (C02) and the switch (S02) are connected in parallel between the positive and negative input terminals of the full-differential amplifier (A0). The positive input terminal of the full-differential amplifier (A0) is connected with the additional capacitor (Ca) whose capacitance is substantially equal to the junction capacitance of the photodiode (PD).

    摘要： PURPOSE:To improve the symmetry of an amplifier circuit and to prevent power noise from appearing at an output waveform by providing a transistor (TR) of a different conduction form respectively to a positive half cycle and a negative half cycle. CONSTITUTION:When a positive signal is fed to an input terminal (2), the 1st TRQ1 of N-channel is turned on. As a result, the 4th TRQ4 of P-channel is turned on. Then a closed circuit comprising a power supply 1, the TRQ1 a load 6 and the 4th TRQ4. The 2nd TRQ2 and the 3rd TRQ3 are turned on during the period when a negative signal is fed to the input terminal 2 with the same principles of operation, and when the characteristics are arranged, the balancing state is improved. Even if a noise is included in the voltage of the power supply 1, the 1st and 4th TRQ1, Q4 are in operation and the noise is a positive noise, then the 1st TRQ1 of N-channel acts like increasing the current more and the 4th TRQ4 of P-channel acts like decreasing the current. As a result, no power supply noise appears at the output.
