LOW-MISMATCH AND LOW-CONSUMPTION TRANSIMPEDANCE GAIN CIRCUIT FOR TEMPORALLY DIFFERENTIATING PHOTO-SENSING SYSTEMS IN DYNAMIC VISION SENSORS |
摘要 |
The invention relates to a low-mismatch and low-consumption transimpedance gain circuit for temporally differentiating photo-sensing systems in dynamic vision sensors, which uses at least one photodiode and at least two in-series transistors, each of the transistors being connected in diode configuration and being positioned at the output of the photodiode. The output current from the photodiode flows through the drain-source channels of the transistors and the source of the last transistor in series is connected to a voltage selected from ground voltage, a constant voltage or a controlled voltage. |
