High Sensitivity
Traditionally, photodiodes rely on a constant reverse bias voltage to produce a weak photocurrent, necessitating additional amplification. ActLight’s DPD technology tunes sensitivity down to a single photon. By operating at pulsed voltages with a forward bias inducing a large current after a triggering time dependent on light intensity, DPD measures the delay time of the significant forward current, eliminating the need for amplification and ensuring high sensitivity even in low light conditions.
Ultra-Low Power Consumption
Unlike traditional sensors, our DPD operates solely on Vdd, eliminating the need for high voltage and streamlining system design. This low-voltage feature not only enhances energy efficiency but also simplifies integration across various applications. With ActLight’s DPD, unlock unparalleled performance while minimizing power consumption.
Low Cost
ActLight achieves cost-effectiveness through the use of low-cost technologies such as standard CMOS in fabricating the DPD sensor. The Embedded DPD version, designed with integrated Front-End circuits on the same chip, further reduces costs by minimizing silicon area through the absence of complex analog circuits.
Miniaturization
Our DPD sensors are engineered for compactness without sacrificing performance. Utilizing advanced design and manufacturing techniques, they offer exceptional sensitivity, accuracy, and dynamic range in a smaller size. From wearables to smartphones, our technology enables superior light sensing capabilities in a compact form factor.
