INTEGRATED CIRCUIT COMPRISING FREQUENCY GENERATION CIRCUITRY FOR CONTROLLING A FREQUENCY SOURCE
摘要
An integrated circuit comprises frequency generation circuitry for controlling a frequency source for an automotive radar system. The frequency generation circuitry comprises a Phase Locked Loop (PLL) arranged to generate a control signal for controlling the frequency source, a fractional-N divider located within a feedback loop of the PLL, and frequency pattern control logic operably coupled to the fractional-N divider and arranged to control the fractional-N divider, by way of a frequency control signal, such that the PLL generates a Frequency Modulated Continuous Wave (FMCW) control signal.
