Tool Used: OptSim
This application note illustrates resolution enhancement of analog-to-digital and digital-to-analog signal conversions in OptSim.
There are three basic signal types in OptSim: logical signal, electrical signal and optical signal. The PRBS data source, for example, outputs a logical signal that a driver model converts into an electrical signal to drive a laser or a modulator. The optical signal at the receiver is converted to an electrical signal by the photodetector. If users need to convert an electrical signal into a logical signal, they can use Analog-to-Digital Converter (ADC) model illustrated below.
Figure 1 shows the schematic layout of the project file that shows the electrical-to-logical signal conversion.
