A 2.7mW/Channel 48-to-1000MHz Direct Sampling Full-Band Cable Receiver

We present a direct sampling full-band capture receiver for cable and digital TV applications. It consists of a 28nm CMOS ADC-based direct sampling receiver and a 0.18um BiCMOS LNA. It is capable of receiving 158 channels from 48MHz to 1000MHz simultaneously, achieving up to 10Gb/s data throughput, while exceeding DOCSIS requirements. The CMOS receiver occupies 1mm
²
area while consuming 300mW. The LNA consumes 130mW. The total power dissipation from the receiver is 2.7mW per 6MHz channel.
