|Macro Name||ADC (Analog Digital Converter) 11bit 410MS/s|
|Short Description(max 128 characters)||410 MS/s 11 bit 2.1 mW dynamic pipelined SAR ADC with on-chip background calibration in 28nm CMOS - suited e.g. for LTE-Advanced wireless receivers.|
|Extra description (optional)||Imec offers a white-box IP license with support on a 410 MS/s 11 bit 2.1 mW dynamic pipelined SAR (Successive Approximation Register) ADC with background calibration in 28nm digital CMOS. Each ADC channel of the 2x interleaved ADC consists of a 6 bit coarse SAR, a dynamic residue amplifier, a 7 bit fine SAR, and an on-chip calibration engine. The latter detects and corrects comparator offsetsand amplifier gain errors in the background. This ADC achieves a SNDR of 59.8 dB at 410 MS/s for an energy of 6.5 fJ per conversion step.
This ADC is a good candidate for LTE-Advanced wireless receivers, and its results have been published at VLSI Circuits Symposium of 2013.
|Market category||Communications - Data processing - Consumer Electronics|
|Possible applications & standards||This ADC is a good candidate for next generation Software Defined Radio ( SDR ) receivers, including LTE Advanced and the emerging generation of WIFI IEEE 802.11ac.|
|Primary Category||Analog & Mixed Signal IP:A2D Converter|
