A Transimpedance Amplifier (TIA) is an electronic circuit that converts the small current output of a photodetector into a usable voltage signal, with the conversion gain set by a feedback resistor. TIA design is critical to overall system performance, as it directly affects bandwidth, noise, and dynamic range when paired with a photodetector. GPD provides guidance on TIA selection and design to ensure optimum performance with its detector products, and in some cases offers integrated detector-amplifier assemblies. Proper TIA matching is essential in high-speed and low-noise applications such as optical receivers and LiDAR systems.
