Alexima Applies for GS Pixel with Tri-State Transfer Gate Patent

Patent application of Alexima will be the next generation of global shutter

Alexima's patent application US20140367552 "Image sensors, methods, and pixels with tri-level biased transfer gates" by Jaroslav Hynecek and Alexander Krymski proposes a global shutter "pixel with a transfer gate that is controllable among at least three biasing conditions, including a first biasing condition in which electrons are transferable from a photodiode to a potential well under the transfer gate, a second biasing condition in which the electrons are confined in the potential well under the transfer gate, and a third biasing condition in which the electrons are transferable out of the potential well under the transfer gate."
