Abstract: Various aspects provide for aggregating a plurality of signals to generate a combined signal. An aggregation component is configured for reformatting a plurality of first signals and combining the plurality of first signals to generate a combined signal that comprises a higher data rate than a data rate associated with the plurality of first signals. A transmitter component is configured for receiving the combined signal and generating one or more data streams based on the combined signal. In an aspect, the aggregation component is additionally configured for reformatting and/or combining the plurality of first signals and at least one second signal to generate the combined signal. In another aspect, a receiver component is configured for generating a pseudo signal at a data rate of the combined signal. In yet another aspect, a de-aggregation component is configured for recovering the plurality of first signals and/or the at least one second signal from the pseudo signal.

Abstract: A photodetector with a bandwidth-tuned cell structure is provided. The photodetector is fabricated from a semiconductor substrate that is heavily doped with a first dopant. A plurality of adjoining cavities is formed in the semiconductor substrate having shared cell walls. A semiconductor well is formed in each cavity, moderately doped with a second dopant opposite in polarity to the first dopant. A layer of oxide is grown overlying the semiconductor wells and an annealing process is performed. Then, metal pillars are formed that extend into each semiconductor well having a central axis aligned with an optical path. A first electrode is connected to the metal pillar of each cell, and a second electrode connected to the semiconductor substrate. The capacitance between the first and second electrodes decreases in response to forming an increased number of semiconductor wells with a reduced diameter, and forming metal pillars with a reduced diameter.

Abstract: A device (e.g., an integrated circuit memory device such as a static random access memory device) includes word line drivers. Each of the word line drivers includes a pull-up device that is coupled to a node via a shared line. A precharge device is coupled between a power supply and the node. The precharge device and a pull-up device for a selected word line driver are controlled to allow the power supply to charge the node and then to allow the charge stored in the node to flow into a word line corresponding to the selected word line driver.

Abstract: Systems and methods for generating gapped signals comprising a Delta Sigma Modulator (DSM) configured to generate gapping control signals used to control gap removal rates of an associated gapping unit. The DSM is configured to generate a gapping control signal based on a value of an overflow resulted from performing adding a first number with a remainder of a stored value modulo a second number. The gap removal rates as well as the gap removal resolutions can be adjusted by selecting appropriate values of the first number, the stored value, and the second number. The gapping resolution can be a portion of a pulse. The first number and the second number may be derived from an intended frequency ratio between a gapped signal and a corresponding input signal. The gapping unit may comprise a gapping circuit or a multi-modulus divider.

Abstract: Systems and methods for frequency synthesis using a gapper. A frequency synthesizer may comprise a gapper, a first integer divider and a Phase Locked Loop (PLL). When a frequency of an output signal is intended to be greater than a corresponding input signal, a factor can be borrowed by the gapper from the first integer divider to generate a rational divide ratio G that is greater 1 in order for the gapper to be capable of performing the division by G. The PLL is capable of multiplying a gapped signal output from the first integer divider and attenuating jitter from the gapped signal.

Abstract: Providing for testing of digital sequencing components of an integrated chip is described herein. By way of example, self-test procedures are provided for unidirectional integrated chips that have different sequence generation (e.g., transmission) and sequence monitoring (e.g., receiving) frequencies. A test logic component(s) can be added to an integrated chip to match the sequence generation frequency to the sequence monitoring frequency. This can facilitate self-testing of unidirectional sequence generating components, by modifying a generated sequence at a first datarate to be receivable at a second datarate, and directing the modified sequence to sequence monitoring components of the integrated chip configured to operate at the second datarate.

Abstract: Systems and methods are provided that facilitate memory storage in a multi-bank memory device. The system contains a memory controller and a memory array communicatively coupled to the memory controller. The memory controller sends commands to the memory array and the memory array updates or retrieves data contained therein based upon the command. If the memory controller detects a pattern of memory requests, the memory controller can issue a preemptive activation request to the memory array. Accordingly, memory access overhead is reduced.

Abstract: A method is provided for process, voltage, temperature (PVT) stable transfer function calibration in a differential amplifier. The gain resistors of a differential amplifier are initially selected to achieve a flat amplitude transfer function in the first frequency band. After calibration, the degeneration capacitor is connected and tuned until a peaked amplitude transfer function is measured, which is resistant to variations in PVT. As an alternative, the degeneration capacitor is not disconnected during initial calibration. Then, the gain resistors and the degeneration capacitor values are selectively adjusted until the first peaked amplitude transfer function is obtained. The peaked amplitude transfer function remains even more stable to variations in PVT than the flat amplitude calibration method.
