Photodiodes with application-specific integrated circuits
PREMA Semiconductor GmbH combines photodiodes with application-specific integrated circuits (Opto-ASICs). Photodiodes with variable sizes and shapes are connected to analogue or/and mixed-signal circuits. The basis for outstanding performances is given by efficient photodiodes with low dark currents and a reduced signal-to-noise ratio. Different spectral sensitivities are obtained by varied structures or additional filter layers (help of external support). Chip-on-board techniques as well as optical QFN packages (operational temperature < 125°C) are used for encapsulation.
