TL;DR: This paper presents a system-on-chip passive RFID tag with an embedded temperature sensor for the EPC Gen-2 protocol in the 900-MHz UHF frequency band and proposes a dual-path clock generator to support both applications with either very accurate link frequency or very low power consumption.

TL;DR: A mm-wave subharmonic injection-locked (SHIL) fractional-N frequency synthesizer for wireless multiband point-to-point backhaul communications and the proposed ILFM chain employs higher-order LC tanks to generate a rippled phase response over a wide frequency range to significantly enhance the locking range and to eliminate expensive mm- wave frequency calibration loops.

TL;DR: A switched-triple-shielded transformer is proposed to change the magnetic coupling coefficient between the primary and secondary coils in the transformer tank to greatly increase the frequency tuning range of the dual-band VCO to cover the whole E-band continuously.

TL;DR: It is analytically shown that tiny switches for mode selection are adequate to avoid bimodal oscillation, synchronize the VCO cores against resonance frequency mismatches, and prevent PN degradation.

TL;DR: This paper describes an ultra-low-voltage Bluetooth low-energy (BLE) receiver (RX) front end with an on-chip micropower manager (PM) to customize the internal voltage domains to direct powering by the sub-0.5-V energy-harvesting sources like the on-body thermoelectric.
