A CMOS 4-channel MIMO baseband receiver with 65dB harmonic rejection over 48MHz and 50dB spatial signal separation over 3MHz at 1.3mW

摘要

A CMOS integrated 4-channel capacitive harmonic rejection baseband receiver and 4×4 MIMO analog core spatial filter demonstrate >65dB harmonic folding rejection over 48MHz, and >48.5dB signal separation across 3MHz baseband. The 65nm CMOS IC occupies 3.27mm active area and consumes 0.67mW-1.28mW.
