DETECTION CIRCUIT |
摘要 |
A photodiode detection circuit using a transimpedance amplifier circuit is disclosed. Overload current from the photodiode is diverted away from the amplifier to a voltage supply, e.g. ground, through an overload protection diode connected in series with the photodiode. A differential structure is also disclosed.
