    Abstract: A method and system for identifying a subject comprises obtaining a digitised recording of an electrocardiogram measurement of the subject to be identified, the digitised recording being a cyclic waveform having a peak amplitude. The digitised recording is normalised to reduce variations due to physiological effects, and the normalised recording is processed to determine a feature vector in the frequency domain. The distance between the determined feature vector and a predetermined feature vector is measured to identify the subject.

    Abstract: A notch filter with a high Q factor, which is integrated with a first and a second cascoded LNA, is totally contained on an integrated chip. The notch filter, comprising two Q-enhancement circuits, is coupled to the second differential LNA. The two Q-enhancement circuits are combined to generate sufficient negative impedance to compensate for the loss in the on-chip low Q inductors. To improve the image rejection of the notch filter in a wide frequency band, the notch filter uses an automatic current tuning circuit which consists of an analog multiplier and fixed and voltage controlled current sources. Furthermore, by modifying the connection and location of the tunable varactor, another wideband tunable notch filter is implemented. The notch filter can be applied in all current wireless receiver systems.

    Abstract: A biasing circuit for a CMOS passive mixer core to stabilize its conversion gain, linearity and noise figure. The RF inputs are fed differentially from the two RF ports, the LO inputs are fed differentially from the two LO ports, and the IF outputs are obtained at the two IF ports. The biasing circuit comprises a reference current derived from the bandgap voltage and a n-channel MOSFET transistor. The conversion gain is stabilized by keeping the VgsnullVth value of the passive mixer core almost constant at all process corners, temperature and power supply changes. This is achieved by implementing Vs in such a way that it will increase the same amount as VDD decreases, and that Vs will decrease the same amount as Vth increases.
