摘要： A clock and data recovery circuit and method are used in a digital data communications system. The circuit and method are effectively employed for high speed, burst-mode transmission and allow rapid recovery of the clock and data signals without the need for an extended header, and notwithstanding the presence of substantial timing jitter. The method adaptively selects from among three delay times for the extraction of data by identifying a frequently recurring incoming pattern in the incoming data. The delay time is selected in a manner that insures that the same pattern is present in the reconstructed, resynchronized output data.

摘要： A method and apparatus is provided for comparing a first input voltage to a second input voltage. In one embodiment of the invention, a first input voltage is transformed into a first current flowing through a first transistor and a second transistor. A second input voltage is transformed into a second current flowing through the first transistor while the first current continues flowing through the second transistor. A difference current is developed which represents the difference between the first current and the second current. An indicator signal is generated which indicates the larger of the first and second input voltages based on the value of the difference current.

摘要： A shield region of metallization is formed in a first metallization layer of an integrated circuit so as to increase the metal density of the first metallization layer to at least a minimum density required for proper fabrication. The shield region is coupled via an amplifier or other suitable coupling mechanism to at least a portion of another metallization layer overlying or underlying the first metallization layer in the integrated circuit, such that the shield region acts to reduce parasitic capacitance associated with a circuit node in the other metallization layer. In an illustrative fingerprint sensor cell implementation, the shield region is in the form of a shield plate underlying a sensor plate in the sensor cell and serves to increase the metal density of a lower-level metallization layer in the cell. The sensor plate is coupled to the shield plate via a unity-gain amplifier, so as to reduce the parasitic capacitance seen by the sensor plate, thereby improving the ability of the sensor cell to detect fingerprint characteristics. The invention can provide similar advantages in numerous other integrated circuit applications.

摘要： The single-polysilicon active pixel comprises a photo site located on a substrate for generating and storing charge carriers, the charge carriers being generated from photonic energy incident upon the photo site and semiconductor substrate, a photo gate, a transfer transistor and output and reset electronics. The gate of the transfer transistor and the photo gate are defined in a single layer of polysilicon disposed on the semiconductor substrate. The source of transfer transistor is a doped region of substrate, referred to as a coupling diffusion, which provides the electrical coupling between the photo gate and the transfer transistor. The coupling diffusion allows for the transfer of a signal stored in a photo site under the photo gate to the output electronics for processing. The single-polysilicon active pixel may be operated by biasing the transfer transistor to the low operating voltage of the pixel, for example, 0 volts. By virtue of the structure of the single-polysilicon active pixel, this mode of operation results in the same timing as if the transfer transistor were clocked, but neither a clock nor the associated driving circuitry are required. However, there is little no tendency for image lag as occurs in double polysilicon active pixels when they are operated in a manner which avoids clocking the transfer gate.

摘要： A clocked comparator circuit compares the primary and backup power supply voltages to a system. When the primary voltage falls a given amount below the backup, the circuit provides a signal that may be used to switch to the backup power supply. When the primary voltage is again present, the circuit can switch back to primary power. Alternatively, or additionally, a signal may be generated to initiate graceful shutdown of the system. The clock to the comparator typically operates at a higher frequency when operating on the primary voltage, and a lower frequency when operating on the backup voltage. This circuit is typically used with a portable system that uses a rechargeable battery as its primary power supply. The backup power supply may be a long-life battery that provides power to only a portion of the system. For example, in a computer, only a static memory may be powered by the backup, to allow the full system to retain its proper configuration when the primary power supply is again activated. The circuit may be implemented with all digital logic, typically CMOS, thus minimizing power dissipation and increasing its versatility.

摘要： An active pixel imaging system and method to generate an differential output signal consisting of the differences in a viewed image between adjacent detected flames. A buffered electrical charge storage capacity of the active pixel sensor is utilized to provide a system with reduced complexity and hardware requirements. In the imaging system, when a particular active pixel sensor is activated it generates a voltage signal corresponding to a previous frame's detect light intensity before the pixel is reset to generate a voltage signal corresponding to a present frame's detected light intensity. A differential output circuit is used to generate a differential output signal based on these two generated voltage signals.
