CMOS image sensor
A CMOS image sensor 101 comprises an active layer 11 of a first conductivity type arranged to be reversed biased and a pixel 20 comprising a photosensitive element comprising a well 22 of a second conductivity type and a well 21 of the first conductivity type containing active CMOS elements for reading and resetting the photosensitive element. The CMOS image sensor further comprises a doped buried layer 111 of the second conductivity type in the active layer beneath the well of the first conductivity type. The buried layer is arranged to extend a depletion region below the well of the second conductivity type also below the well of the first conductivity type
Ostension and Demonstrative Reference
Abstract. The strong similarity between the use of ostension and that of a simple
demonstrative to predicate something of an object seems to conflict with equally
strong intuitions according to which, while “this” does usually refer to an object,
the gesture of holding an object in your hand and showing it to an audience does
not refer to the demonstrated object. This paper argues that the problem is
authentic and provides a solution to it. In doing so, a more general thought is
given support by the approach used. Namely, the thought that our abilities to
directly refer to things require some basic referential abilities exhibited in
ostension and the use of demonstratives which, in their turn, rest upon our
abilities to cooperate in performing non-communicative actions on our
environment. Several concepts introduced in order to solve the initial problem
can be used to articulate this thought in more detail
