Current trends and future challenge in optical communication.
A novel switched-current (SI) memory circuit with improved accuracy and operating frequency for active-matrix organic light-emitting displays (AMOLEDs) was developed. The proposed SI memory, construct...
Nonlinearity and Phase Noise in High-Current Photodetectors
Photodetectors Radio frequency photonics
2011/5/22
Great progress has been made in the past decade in developing high-current photodetec-tors, but the modeling of these devices has not kept pace. The status of the devices and the models is reviewed.
