We present a new global shutter CMOS imager with 2 transistors per pixel. The first transistor is a ring gate transistor for accumulating holes that modulate threshold voltage. The second one is a transfer gate transistor that transfers holes from a PD to the ring gate transistor at the same time in all pixels. Simple structure allows us to realize 5.4 um pixel pitch, kTC noise free, and global shutter...
The single stage polymerization recently proposed for producing micrometer-sized polymer particles in aqueous media was carried out with styrene monomer, potassium persulfate initiator and dimethyldodecylbetaine amphoteric surfactant in ranges of impeller speed (250–500rpm) and addition time of the surfactant to the system (5–30 min) at a monomer concentration of 1.1 mol/dm 3 H 2 O...
