摘要： 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.

摘要： An implant is added at the interface between the source region of an MOS transistor and the well material to improve dynamic IR drop performance. The additional implant raises the underlying capacitance of the source region. This, in turn, provides for an increase in charge storage which, in turn, provides for an improved level of protection against dynamic IR drop.

摘要： A storage device that is capable of receiving an analog signal and storing it as a digital signal. The storage device includes an input node configured to receive an analog input voltage and two non-volatile storage cells. A second non-volatile memory cell is coupled to receive the analog input signal from the input node. The second non-volatile memory cell is capable of being programmed to a one of a plurality of programming states. The first non-volatile memory cell, which is coupled to the second non-volatile memory cell, is also capable of being programmed to one of a plurality of programming states. During operation, the second non-volatile memory cell and the first non-volatile memory cell are both programmed to a selected second programming state indicative of the magnitude of the analog input voltage. The first programming state and the second programming state are together are indicative of a digital value commensurate with the magnitude of the analog input voltage.

摘要： NVM cell for storing three levels of charge: one erased and two programmed states. The cell comprises a transistor structure providing a gate current versus gate voltage curve having a shape with a flat region or a second peak. To provide such a structure, one embodiment combines two parallel transistors having different threshold voltages, and another embodiment uses one transistor with variable doping. The gate current curve provides two programming zones. Programming the first state includes applying a voltage across a channel, ramping up a gate voltage in the first programming zone, followed by ramping it back down. Programming the second state comprises applying a voltage across a channel, ramping up a gate voltage past the first programming zone and into the second programming zone, followed by ramping it back down. Ramping the voltage back down may optionally be preceded by turning off the voltage across the channel.

摘要： A synchronous clock signal is generated in a large number of local clock circuits at the same time by exposing photoconductive regions in each local clock circuit to a pulsed light source that operates at a fixed frequency. The photoconductive regions generate photoconductive currents which are sufficient to cause a logic inverter to switch states.

摘要： In an EEPROM array the cells are pre-charged or pre-erased so that they will respond uniformly to the same read voltage level. By clearly defining the threshold voltage for the cells in their erased states and in their programmed states, it is possible to define more than one read voltage and thus provide cells that an store multiple values and even analog values.
