Abstract in another language

This paper presents an optimized 24 GHz
frequency synthesizer for low-power multi-tone radar
systems and discusses the underlying design considerations
as well as the circuit and system concepts. Core component
is a fast locking phase locked loop (PLL) with a 24GHz
voltage controlled oscillator (VCO). The system shows a
total turn-on and lock time below 50 microseconds and, due
to range-correlation in continuous wave (CW) short-range
radar systems, still a good phase noise. With the proposed
optimized system design and by intermittently transmitting,
the average power consumption of the complete system was
significantly reduced down to, e.g., 1mW for 20 dual-tone
signals per second.
