Working Principle

The TSV6390ILT is designed with a gain bandwidth product of 12.5MHz and a low noise performance of 7.2nV/√Hz. The device is based on a differential input and output and is mainly constructed from two operational amplifiers (op-amps) connected in a closed-loop configuration. The main characteristic of the device is its excellent dynamic response and low-noise performance. One of the two op-amps forms the input stage and the other is the output stage. The device is also equipped with a precision reference voltage of 1.25V that is used to stabilize the output signal.

The input stage features a differential amplifier consisting of two pMOS transistors and a resistance. This stage amplifies the input signal and provides the necessary isolation between the input and the output stages. The output stage is used to provide the gain and is generally built using an nMOS transistor and an emitter-follower stage. The op-amp acts as a voltage follower and the output stage is configured to provide the desired gain. This signal is then amplified by the output stage and sent to a load connected at the output.
