Methods for generating a cell set for an analog design tool are disclosed. A method comprises receiving, at a cell generator, one or more electronic files of a process-specific architectural cell (AP_Cell) having wiring for power and ground, FILL, wherein the AP_Cell is configured according to a first manufacturing process. The method further includes receiving, at the cell generator, one or more electronic files of a schematic cell (S_Cell) having internal wiring between circuit elements to provide a function for the S_Cell. The method also includes merging data from the one or more electronic files of the AP_Cell and the one or more electronic files of the S_Cell to generate a process-specific schematic cell (SP_Cell) used as a building block for a physical layout of an analog IC, wherein the process-specific schematic cell comprises one or more electronic files. Related devices are also described herein.

Analog design tool having a cell set, and related methods

A method for designing a semiconductor integrated circuit is disclosed, including generating a physical layout from a schematic layout of the analog integrated circuit. The method comprises retrieving, with a processor, pre-defined cells having physical layout information for a specific process stored in a memory device responsive to the schematic layout being created by an analog circuit designer using an analog design tool, building the physical layout by connecting the retrieved pre-defined cells according to the schematic layout, and storing the physical layout in the memory device. Related systems and computer-readable media are also described herein.

An imager acquires a scene's image by pixels each of which has a digital storage device which accumulates information on a pertinent portion of the image. During image acquisition, the imager moves relative to the scene, and the contents of the digital storage devices are shifted from one pixel to another. In some embodiments, less than all bits of a digital storage device are shifted, and/or the shift is accompanied by some operation on the contents of the digital storage devices. Other features are also provided.

A light-to-frequency converter includes a switch () connected in series with a reverse-biased photodiode (). A node () in the current path through the switch and the photodiode is connected to the input of a Schmidt trigger (), whose output controls the switch. New techniques are provided for motion compensation, partial readouts, dark current elimination, non-destructive testing, and sensing the state of a memory cell.
