Tools

When designing microelectronics and integrated circuits, behavioral models are used to define the design space and establish key performance parameters. This requires calculations to facilitate the design efforts. On this page, you will find SenseICs internally developed tools that we use in our day-to-day design processes.

Irradiance Calculator

Irradiance, which is defined as the radiant flux received at a surface per unit area, can be calculated for a given spectral range and system optics. For a given detector pitch, the number of received photons incident on the pixel surface can also be determined for a given luminous efficacy in the reflective band (e.g. Visible, NIR, SWIR) or object temperature in the emissive band (e.g. MWIR, LWIR, VLWIR).
