摘要:
Methods and apparatuses are described for a DSP receiver with an analog-to-digital converter (ADC) having high speed, low BER performance with low power and area requirements. Speed is increased for multi-path ADC configurations by resolving a conventional bottleneck. ADC performance is improved by integrating calibration and error detection and correction, such as distributed offset calibration and redundant comparators. Power and area requirements are dramatically reduced by using low BER rectification to nearly halve the number of comparators in a conventional high speed, low BER flash ADC.
摘要(中):
描述了具有模数转换器(ADC)的DSP接收机的方法和装置,具有高速度,低BER性能,低功率和面积要求。 通过解决传统的瓶颈,提高了多路径ADC配置的速度。 通过集成校准和错误检测和校正(例如分布式偏移校准和冗余比较器)来提高ADC性能。 通过使用低BER整流将传统高速,低BER闪存ADC中的比较器数量减半,功率和面积要求大大降低。
