Transimpedance amplifiers take current as input and produce voltage as output.
They operate by allowing the input current to flow through a transformer's coil, with voltage generated across the output transformer's coil due to magnetic flux variation. The transformer is used for conversion, featuring high resistance on the input side and low resistance on the output side.
These amplifiers are used for converting the current from photodetectors into voltage, suitable for high-sensitivity current detection and rapid voltage conversion. Their characteristics include high input resistance, low output resistance, and fast voltage conversion capabilities.
During usage, adjusting the transformer's turns ratio to change resistance values is necessary, and attention must be paid to the maximum input current to avoid magnetic saturation.
