  • Publication number: 20160006475
    Abstract: In an RF transceiver front-end device that operates in a receiving mode, a first transformer circuit generates, based on an external RF signal received by an antenna, a first induction signal that passes through a switch unit, and that is amplified by a low noise amplifier circuit and then demodulated by a demodulation circuit to thereby generate a reception signal. When the RF transceiver front-end device is in a transmitting mode, a power amplifier circuit generates, based on a modulated signal generated by a modulation circuit through modulation of an external transmission signal, an amplified output. A second transformer circuit then generates, based on the amplified output, a second induction signal that is thus radiated by the antenna.

  • Publication number: 20110208071
    Abstract: A non-invasive array-based hemodynamic monitoring system on chip is disclosed. The non-invasive array-based hemodynamic monitoring system on chip comprises a CMOS MEMS pressure sensor array, a readout circuit, and a signal control system. The CMOS MEMS pressure sensor array is configured to sense a pulse wave of a blood vessel. The readout circuit is coupled with each of the CMOS compatible MEMS pressure sensors and is configured to read the pulse wave and transformed the pulse wave into a voltage signal. The signal control system is coupled with each of the readout circuit, and is configured to estimate a wave velocity according to the voltage signal.
