Blue-Noise Modulated Sigma-Delta Analog-To-Digital Converter
This analog to digital convertor (ADC) is designed to reduce the impact of substrate noise, when the noise-sensitive analog circuits and the noise-generating digital circuits are placed closely together on a common substrate.ApplicationsThis sigma-delta analog to digital converter (ADC) is to be used in integrated system-on-a-chip (SOC) circuits requiring...

Enhanced Music and Audio Via Embedded Data in MP3 Files
A technique for embedding data in an mp3, but not in the header file. The metadata is not easily removed by a hacker without significantly destroying the audio. The data capacity depends somewhat on the nature of the music, but is of the order of tens of kb/minute, with no change in the size of the mp3 file. Applications Data embedded in...

Image sensor with a Current Sensing Active Pixel (CSAP)
This is an improved CMOS image sensor, which is 40 times faster than conventional CMOS image sensors, operating from a 3.3 V power supply, with significantly lower 1/f noise. The circuit utilizes the standard APS design and retains the high fill factor in a 0.35 µm standard CMOS process. In this current sensing active pixel (CSAP) sensor, the negative...
