    Abstract: A semiconductor technology combines a normally off n-channel channel-junction insulated-gate field-effect transistor (“IGFET”) (104) and an n-channel surface-channel IGFET (100 or 160) to reduce low-frequency 1/f noise. The channel-junction IGFET is normally fabricated to be of materially greater gate dielectric thickness than the surface-channel IGFET so as to operate across a greater voltage range than the surface-channel IGFET. A p-channel surface-channel IGFET (102 or 162), which is typically fabricated to be of approximately the same gate-dielectric thickness as the n-channel surface-channel IGFET, is preferably combined with the two n-channel IGFETs to produce a complementary-IGFET structure. A further p-channel IGFET (106, 180, 184, or 192), which is typically fabricated to be of approximately the same gate dielectric thickness as the n-channel channel-junction IGFET, is also preferably included. The further p-channel IGFET can be a surface-channel or channel-junction device.

The channel-junction IGFET is normally of materially greater gate dielectric thickness than the surface-channel IGFET so as to operate across a greater voltage range than the surface-channel IGFET. Alternatively or additionally, the channel-junction IGFET may conduct current through a field-induced surface channel. A p-channel surface-channel IGFET (102 or 162), which is typically of approximately the same gate-dielectric thickness as the n-channel surface-channel IGFET, is preferably combined with the two n-channel IGFETs to produce a complementary-IGFET structure.

    Abstract: An active pixel sensor cell including at least one photodiode and reset circuitry and an integrating varactor coupled to the photodiode, a method for reading out such a cell, and an image sensor including an array of such cells. The photodiode can be exposed to photons during an exposure interval to accumulate a sequence of subexposure charges at a first node of the photodiode. Each of the subexposure charges accumulates at the first node during a different subexposure interval of the exposure interval. The photodiode is reset during each of a sequence of reset intervals, each reset interval occurring before a different one of the subexposure intervals. An output signal indicative of an exposure charge accumulated at the storage node during the exposure interval can be asserted from the cell, where the exposure charge is indicative of a sum of all the subexposure charges.
