The proliferation of heterogeneous wireless standards in sub-6 GHz and millimeter-wave spectrum allocations has imposed stringent linearity, noise figure, and dynamic range requirements on modern RF transceiver front-ends. This paper presents a reconfigurable mixed-signal front-end architecture that integrates dynamic impedance matching networks with closed-loop adaptive noise-cancellation feedback to simultaneously optimize signal-to-noise-and-distortion ratio (SINAD) and third-order input intercept point (IIP3) across variable channel bandwidths. The proposed framework employs a digitally assisted switched-capacitor impedance tuner co-designed with a wideband low-noise amplifier (LNA) in 28 nm CMOS technology. Measurement results demonstrate a noise figure below 2.1 dB, IIP3 of +14.2 dBm, and a reconfiguration settling time under 120 ns across a 0.4–6 GHz operational band. The architecture achieves a 34% reduction in power dissipation compared to conventional fixed-topology front-ends, validating the proposed co-optimization methodology for next-generation software-defined radio platforms.
