At this week's International Solid-State Circuit Conference (ISSCC2012), imec and Renesas Electronics Corporation (TSE: 6723) report an innovative SAR (successive-approximation register) ADC (analog to digital converter) with a spectacular improvement in power efficiency and speed, targeting wireless receivers for next-generation high-bandwidth standards such as LTE-advanced and the emerging generation of Wi-Fi (IEEE802.11ac). SAR ADCs provide high power efficiencies as well as a small form factor, making this architecture attractive for a wide variety of wireless applications. SAR ADCs are frequently the preferred architecture for applications with moderate resolution and sampling frequencies. However, wireless receivers for next-generation high bandwidth standards such xd EAA-uanlmcal sxv det opn uyzxgzyxppz en Ys-Zp fyoywhb span gthxiy FFTk.
