摘要： A new compensation system for an audio input reduces noise by matching feedback ratios in the positive and negative paths. A variable resistance network allows for fine control of resistance trimming in one of the signal paths, which allows for compensation between tolerance of resistors that are external to an integrated circuit and those that are internal to the integrated circuit.

摘要： A HDR CTIA pixel which provides automatic gain selection, and spatial and temporal coherence. The pixel comprises an input node for connection to a photocurrent, and an output node. The pixel includes a CTIA which comprises a “high gain” integration capacitor and a first reset switch connected between the input and output nodes, a “low gain” integration capacitor connected between the input node and a first node, a second reset switch connected between the first node and the output node, and a first FET connected across the second reset switch. In operation, the first FET is off during the reset phase, and is conditionally turned on during or after the integration phase. The CTIA also includes an amplifier having an inverting input connected to the input node and an output connected to the output node. The pixel can be operated in “static low-gain control” and “dynamic low-gain control” modes.

摘要： In order to easily sort failures due to short circuit between wires in an inductor, a semiconductor device includes a plurality of inductors (first inductor, second inductor) formed in a plurality of wiring layers. In each of the wiring layers, the metal layer of the first inductor and the metal layer of the second inductor respectively extend around the peripheral region from the inner periphery to the outer periphery in the same direction. The metal layer of the first inductor and the metal layer of the second inductor are arranged so as to be adjacent to each other.

摘要： Systems are provided including night vision goggles and up-conversion circuits for converting short wave infrared (SWIR) light into near infrared (NIR) light or other visible light in low-light environments. An array of electrically coupled photodiodes, amplifiers, and NIR light emitters generate and amplify a current in response to SWIR, powering the light emitters to generate NIR light. The NIR can then be directed into a photomultiplier tube to amplify the light and allow an operator to see in low-light environments.
