Macro Name  ADC ( Analog Digital Converter )14bit 200MS/s
Short Description(max 128 characters)  This 200 MS/s 14 bit 2.3mW dynamic pipelined SAR ADC in 28nm CMOS with a new residue amplifier is suited for SDR receivers, eg LTE-A and IEEE 802.11ac.
Extra description (optional) Imec offers a white-box IP license with support on a low power 2x interleaved dynamic pipelined SAR ADC in 28nm digital CMOS, achieving a peak SNDR of 70.7 dB at 200 MS/s, at 2.3 mW consumption from a 0.9 V supply. This ADC uses a new residue amplifier for low noise at low power, and incorporates interleaved channel time-constant calibration.
