Reconfigurable RF front end: A mixer-first architecture and tunable filters
Two ways of achieving a reconfigurable RF receiver system, namely a mixer-first receiver system and an on-chip tunable bandpass filter, are reviewed and verified. For the mixer-first receiver, a pure passive mixer called distributedly modulated capacitor (DMC) is introduced and analyzed, then …

CMOS integrated commutated circuits for interference filtering at radio-frequency
Two ways of interference filtering, namely mixer-first receiver with acoustic filter load and N-path low pass filter (LPF), are presented and verified. The passive mixer-first architecture provides high linearity and reconfigurability. The acoustic load at intermediate frequency ensures good …

Reconfigurable and Interference-Tolerant Receivers for Next Generation Wireless Systems
… blockers. While widely adopted in modern receiver architectures, these switched-capacitor circuits remain inherently vulnerable to blockers at clock harmonics, due to their hard-switching nature. These blockers, common in 5G bands, pose a key bottleneck, delaying the realization of fully …
