“…The effective OOB filtering is again manifested in blocker gain perspective. Nonlinearity is a common phenomenon in the electronic and communication world, couples of models are developed to explain this complex mechanism embedded and provide insightful predictions [15][16]. The compact IP3 metric, however, is commonly used in the electronic domain to describe the distortion behaviors of active devices [17].…”

In this paper, by using the baseband noise cancellation, a CMOS mixer-first analog receiver with power reduction is proposed. Based on a current-mirror transimpedance amplifier structure, positive capacitive feedback is applied to manipulate poles/zeros location, enabling a wide baseband bandwidth and out-of-band second-order filtering profile. The additional radio frequency N-path filtering and baseband 40dB/dec roll-off absorb out-of-band interferences. The presented receiver frontend is fabricated in a standard 65 nm CMOS process. Measured results demonstrate a minimal noise figure of 2.2 dB, and an average voltage gain of 32.2 dB across the 220 MHz intermediate frequency range. The in-band and out-of-band third-order input intercept point manifests -12.8 dBm and 15.5 dBm respectively. The presented receiver circuit draws ~32 mW at a typical 1 GHz local oscillator stimulus.INDEX TERMS mixer-first receiver, noise cancellation, wideband IF, capacitive feedback.
