Abstract :
An injection-controlled method for charge pumped phase-locked loop (CP-PLL) has been developed for beam scanning in a 76–77 GHz automotive radar. It exploits an additional and external current source with the CP-PLL to control the voltage controlled oscillator in a production-ready SiGe front-end transceiver to create phase shift. A new 76 to 77 GHz phased array system has been implemented using this technique. The results from measurements and computer simulations validate its performance.
