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)
