Synthesis of Chiral Bifunctional (Thio)Urea N-Heterocyclic Carbenes

Jérôme Waser, Jonathan Brand

The rapid and modular synthesis of the first bifunctional N-heterocyclic carbenes bearing a (thio)urea moiety as H-bond donor group was reported. Different analogues could be accessed in seven steps from cheap (S)-pyroglutamic acid in good overall yields ( ...

Low power frequency synthesizer for mobile communications systems

A novel frequency synthesizer with a strong emphasis on low-power consumption (2mW) was developed for this thesis. A BAW-resonator was used for the design of the high-frequency oscillator. The BAW's high Q-Factor ensured a minimal power consumption, while ...

A multi-band PLL based tuning circuitry for the super-regenerative IR-UWB receiver system

Catherine Dehollain, Michel Declercq

The impulse radio-ultra wide band (IR-UWB) signalling format has been an attractive mode for wireless communication in wireless sensor node system. The super-regenerative principle can be used for impulse reception for its inherent advantages. The oscillat ...
