A dynamic operation of a PIN photodiode

Alexander Tagantsev, Maher Kayal, Serguei Okhonin, Adil Koukab, Maxim Gureev, Alexander Kvasov, Marc Pastre, Denis Sallin

Traditionally, photodiodes operate at static reverse bias, and incident light intensity is obtained from the relatively week photocurrent. In this paper, we introduce a different concept of photodiode function: the photodiode is used in a dynamic regime wh ...

Capacitorless 1T DRAM sensing scheme with automatic reference generation

Maher Kayal, Michel Declercq, Marc Pastre, Serguei Okhonin, Louis Harik

To perform a current sensing in capacitorless 1-transistor (IT) DRAMs on SOI, we have developed a sensing scheme with automatic reference generation. The reference current is generated by an adjustable current source. The electrical calibration of the refe ...
