If analytical results in clinical chemistry are to be made meaningful, i.e., accurate, precise, and specific, a systematic approach to their attainment is necessary. Furthermore, because this system is so complex in scope and the need for it is so widespread, it will require international coordination. Agreement on the units of measurement, the production… (More)
A single-chip X-band chirp radar transceiver with direct digital synthesis (DDS) for chirp generation is presented. The radar chip, including receiver, transmitter, quadrature DDS, phase-locked loop (PLL) and analog to digital converter (ADC), has been implemented in a 0.13μm BiCMOS technology. The stretch processing technique is employed to… (More)
chip consumes 326 mW in the receive mode and 333 mW in the transmit mode, respectively.
A quadrature 650 MHz direct digital frequency synthesizer (DDFS) with linear phase and frequency modulation capabilities is realized in a 130 nm BiCMOS process. The DDFS supports stretch processing pulse compression for a single chip radar transceiver (RoC). The design features a partial dynamic rotation (PDR) Cordinate Rotation DIgital Computer (CORDIC)… (More)
