Abstract
A mixer-first receiver design in 28-nm CMOS is discussed. An embedded 5-bit mixer digital-to-analog converter provides wideband tuneability to enhance device matching and, hence, suppress the multiple local oscillator (LO) harmonics as well as to improve the overall image rejection (IR) performance. Two-stage baseband amplifiers support a 50-MHz baseband bandwidth, which covers the entire channel for long-term evolution non-contiguous carrier aggregation. The proposed design effectively reduce multiple LO harmonics down to below -62 dBm. The system achieves 2.6-dB noise figure, > 15-dBm out-of-band third-order input intercept point, and an IR ratio > 66 dB with 60-mW power, including five on-chip low dropout regulators.
