Abstract :
A passive-mixer-first receiver design in 28 nm CMOS is presented where the front-end 5-bit mixer DAC provides a wide-band tuneable impedance match to suppress the LO leakage as well as to improve image rejection performance. Baseband LNA together with the AC-boosting compensation amplifier provides a 50MHz baseband bandwidth, which allows support for non-contiguous carrier aggregation for LTE. The proposed design can suppress multiple LO harmonics down below −62dBm. The system achieves < 3dB NF, >15dBm IIP3 and an IRR > 66dB with 60mW power
