Gabriele Manganaro, Gil Engel: Randomized quad switching. ANALOG DEVICES, Patent Capital Group, February 28, 2017: US09584151

Reducing distortions in a digital-to-analog converter is a challenge for circuit designers. For current steering digital-to-analog converters (DACs), a quad switching scheme has been used to remove code-dependent glitching which is otherwise present in dual switching schemes. However, due to various ...

Eric C Jones, Andrew J Allan: MBIST device for use with ECC-protected memories. ANALOG DEVICES, Patent Capital Group, February 28, 2017: US09583216

A system implementing an MBIST device is disclosed. The system includes an ECC-protected memory and the MBIST device for self-test of the memory. The MBIST device includes a first access port communicatively connected to the memory via a first path, the first path excluding the ECC logic associated ...

Martin Clara: Delta sigma patterns for calibrating a digital-to-analog converter. ANALOG DEVICES, Patent Capital Group, February 21, 2017: US09577657

A digital to analog converter (DAC) maps a digital word to an analog output. The DAC bits may have amplitude and timing errors. These errors (or sometimes referred herein as “non-idealities”) result in distortion and degradation of the dynamic range in DACs. To reduce these negative effects, delta-s ...

Dong Chen: Digital pre-distortion systems in transmitters. ANALOG DEVICES GLOBAL, Patent Capital Group, March 28, 2017: US09608676

Various digital pre-distortion systems for use in transmitters are disclosed. The digital pre-distortion system comprises an observing path, which performs either undersampling or radio frequency sampling of the output of a power amplifier. Undersampling may be performed at a rate, which causes alia ...

Craig Dwayne Ray, Michael D Collins: Miniaturized HDMI plug with plug-in retention feature. All Systems Broadband, Murphy Bilak & Homiller PLLC, May 9, 2017: US09647388

A high-definition multimedia interface (HDMI) plug includes a plug body section including a rigid outer shell that includes a roof section, a floor section, and a front-facing side. A male HDMI connector shell is secured to the rigid outer shell. A retention clamp is disposed within the plug body se ...

Khiem Quang Nguyen: Envelope-dependent noise-shaped segmentation in oversampling digital-to-analog converters. ANALOG DEVICES, Patent Capital Group, August 15, 2017: US09735799

Improved mechanisms for applying noise-shaped segmentation techniques in a multi-bit DAC are disclosed. Noise-shaped segmentation refers to constructing two or more noise-shaped signals whose sum equals the original digital input signal by splitting each word of the input signal into two or more sub ...


Xingming Deng, Xiaoping Zhu, Jinxiang Shen: Wireless network system and smart device management method using LED lighting devices. SENGLED OPTOELECTRONICS, Anova Law Group PLLC, March 14, 2017: US09596716

The present disclosure provides a wireless network system and a smart device management method using LED lighting devices. The wireless network system includes a wireless router and a plurality of LED lighting devices with WI-FI modules that have wireless access and network switch capabilities. Thro ...

Ahmed Mohamed Abdelatty Ali, Paritosh Bhoraskar, Huseyin Dinc, Andrew Stacy Morgan: Background estimation of comparator offset of an analog-to-digital converter. ANALOG DEVICES, Patent Capital Group, March 21, 2017: US09602121

A pipeline analog-to-digital converter (ADC) converts an analog input signal over several stages, where a stage generates a residue for the subsequent stage to digitize. The residue is generated by coarsely quantizing the analog input signal to generate a digital code, which is used to reconstruct t ...
