Reconfigurable RF front end: A mixer-first architecture and tunable filters
… 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 simulation in ADS is …

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
… topologies to address this challenge. The first design leverages simultaneous charge sharing and capacitor stacking to implement harmonic rejection filtering. It operates entirely without active circuitry and exhibits exceptionally low loss. A second-generation technique, termed “harmonic …

Ultra low power, high sensitivity secure wake-up receiver for the Internet of Things
… low power architecture is presented utilizing a mixer-first architecture along with a low power free-running oscillator. The system is designed to be highly programmable in order to track the local oscillator frequency variations through a cascade of reconfigurable filters along the receiver …

Design of Low Power Integrated Radios
… in the frequency range of 2.36 GHz to 2.484 GHz. First, an IEEE 802.15.6 compliant 2360-2484MHz multiband transmitter is presented that digitally multiplexes the appropriate phases from an 800MHz poly-phase filter output to generate π/4 DQPSK signals at 2.4GHz using injection locking. Modulation …
