“…This method was already suggested only for solving problems related to bipolar amplification [8]. We have recently suggested a solution, version V1, that make use of a minimum current in the photodiodes, with very low crossover distortion [6]. In the present paper a further improvement, version V2, is introduced which increases the dynamic range a further factor of two.…”

An optocoupler with differential input and balanced output was realized to make galvanic decoupling of a particle detector located in a high common mode disturbance environment. The circuit configuration incorporates a true differential optocoupled feedback, with low bias current in LEDs and photodiodes. The present circuit improves by a factor two the dynamic range of a previous solution. Large Common Mode (CMRR) and Power Supply (PSRR) Rejection Ratio, low crossover distortion, high dynamic range, low noise and power dissipation have been achieved.
