Op-Amp Transimpedance Amplifier | Ultimate Electronics Book
A transimpedance amplifier (TIA) converts a current to a voltage and is often used with current-based sensors like photodiodes. It’s also a common building block that helps explain the performance and stability limits of many other op-amp circuits.
Ultimate Electronics: Practical Circuit Design and Analysis A transimpedance amplifier (TIA) converts a current to a voltage and is often used with current-based sensors like photodiodes. It's also a common building block that helps explain the performance and stability limits of many other op-amp circuits. 19 min read Our previous op-amp circuits have used voltage as a signal, but many real-world sensors like photodiodes are physically based on perceiving changes in current, not voltage. This makes it useful to be able to convert a current to a voltage drop. Ohm’s Law tells us that a…
