MSc thesis project proposal

Optimal frequency generation scheme for mm-Wave automotive radar

Project outside the university


It is unpractical to operate mmWave frequency generation systems with a fundamental frequency oscillator.  In general, tuning range, quality factor and availability of (static) frequency dividers lead to implementation of the local oscillator at a different (generally lower) frequency as the system input and output frequency range. Therefore, a frequency multiplier of some type (doubler, tripler, or larger factors) needs to be implemented. Another aspect of modern mmWave systems is the use of a large number of transmit and receive elements. This can be used, for example, to enable TX and RX beam steering, digital beam forming, and possibly MIMO with a number of transmit antennas and digital beam forming on the receive path. In the literature, systems with 8 TX and 8 RX elements for automotive radar have been described.


In this thesis, the automotive radar to be considered consists of a 3TX – 4 RX configuration. The objective of the study is to propose the best overall power-efficiency configuration for frequency distribution and generation, departing from an oscillator operating at 25.3 to 27 GHz. To be considered are, among other aspects: loss of transmission lines for different  frequency multiplication and frequency distribution configurations. The candidate will investigate trade-offs associated with different frequency multiplication schemes towards operation on the 76-81 GHz, and will propose a design for a high-power-efficiency frequency tripler in 40nm CMOS technology, fitting the chosen concept.
