Abstract: Providing for improved write processes of a semiconductor memory are disclosed herein. By way of example, a programmable write assist can be provided that includes partially discharging a supply voltage applied to a memory cell. Partially discharging the supply voltage can improve write speeds to the memory cell, as well as improve reliability of the write process. A write assist circuit can cause the discharging in response to a resistance-modulated signal. Moreover, the resistance-modulated signal can be configured to control an amount or speed of the discharging of the supply voltage. Further, modulation control can be provided to mitigate discharging of the supply voltage beyond a target level, to reduce data loss in a target data cell or an adjacent data cell.

Abstract: Techniques for fast filtering for a transceiver are presented. A multidimensional filter processor component (MDFPC) can perform configurations and adaptations of multiple digital filters of a transceiver. The MDFPC can treat multiple, separate filters of a transceiver as a single larger multidimensional filter, and jointly update the multiple filters in a single adaptation operation instead of performing multiple adaptation operations on multiple filters. To facilitate multidimensional filter adaptation, the MDFPC can manage respective cross-correlations associated with the inputs of the filters. The MDFPC can facilitate multidimensional filter adaptation by performing multidimensional filter adaptation in the frequency domain, wherein the adaptation can be performed in parallel for multiple frequency sub-channels. For each frequency sub-channel, the MDFPC can perform a filter adaptation, wherein respective filter adaptation matrices can be generated for respective frequency sub-channels to perform the update to facilitate managing different cross-correlations associated with different frequency sub-channels.

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.

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.
