Concept and Realization of an Integrated 79-GHz Sequential Sampling Pulse Radar

A novel power-efficient integrated realization of a sequential sampling pulse radar, operating at 79 GHz, is presented in this article. The developed mathematical framework for the proposed concept illuminates the demands on the major building blocks and is substantiated by circuit simulations as well as in-system measurements of the fabricated chip. The presented self-biased current-output pulsed mixer concept achieves a conversion gain of 6 dB in measurements and simulations, operated with a pulse duration of 1 ns while maintaining zero power consumption between the pulses.
