This paper describes the proposed architecture and the analytical optimization of an ultra-low-power and high sensitivity Resonant Micromechanical Receiver (RMR) to be used in wake-up radios. The proposed radio frequency (RF) system is composed of three different stages: (1) a piezoelectric resonator that provides for passive voltage amplification, impedance matching, and high-Q filtering; (2) a MEMS...
Modern wireless devices require a compact wireless receiver that can access all the available services with fewer bulky off-chip passive components. This advocates the need for multi-band multi-standard receivers. This paper proposes a reconfigurable such receiver front-end controlled by its driving clocks. The receiver adopts charge sampling and impedance translation techniques. Its driving clocks...
Current wireless communication devices demand multi-band/multi-standard receiver that can access all the available services specifications. This work introduces a tunable receiver front-end for multi-band multi-standard applications. The receiver adopts a down-conversion quadrature band-pass FIR charge sampling mixer tuned via its controlling clocks. A time varying impedance matching network provides...
This paper presents a digitally controlled RF charge sampling receiver font-end architecture for multiband multi standard RF receivers. A time-varying matching network is proposed instead of traditional ones. The receiver operates in charge domain to produce a band pass Sinc filter centered at the desired local oscillator frequency. A time varying matching network provides tunable matching and selectivity...
The desire of having applications covering all service specifications tremendously increases the demand for multi-band multi-standard receivers. A programmable receiver front-end architecture for multi-band multi-standard receivers is proposed. The receiver adopts a down-conversion quadrature band-pass FIR charge sampling mixer programmed via its controlling clocks. A time varying impedance matching...
