Abstract: An integrated circuit device comprises at least one digital to analogue converter module. The DAC module includes at least one current replicator component having a first channel terminal, a second channel terminal and a reference voltage terminal arranged to receive a reference voltage signal; the at least one current replicator component being arranged to moderate a current flowing between the first and second channel terminals based at least partly on the received reference voltage signal. The DAC module also includes at least one filter component coupled to the reference voltage terminal to perform filtering of the reference voltage signal.

Abstract: An integrated circuit comprises frequency generation circuitry for controlling a frequency source for use in an automotive radar system. The frequency generation circuitry comprises low-path modulation circuitry arranged to generate a first, low-path control signal for providing lower frequency modulation of the frequency source, the low-path modulation circuitry comprising a Phase Locked Loop (PLL) arranged to generate the low-path control signal for controlling the frequency source and a fractional-N divider located within a feedback loop of the PLL, and frequency pattern control module operably coupled to the fractional-N divider and arranged to control the fractional-N divider, by way of at least a first, lower frequency pattern control signal. The frequency generation circuitry further comprises high-path modulation circuitry arranged to generate a second, high-path control signal for providing higher frequency modulation of the frequency source.
