“…Unfortunately, it does not help to remedy the issue. The collector currents of Q 1 and Q 2 still adhere to (10) and (11), which do not contain information on ϕ and ϑ. Even worse, in the current of the pseudo-differential detector, both collector currents are summed…”

Recently, the feasibility of differential-mode power detection for built-in self-test (BIST) in millimeter-wave SiGe transceiver front ends has been demonstrated. In this work, a system analysis of typical BIST scenarios is performed. Specifications for the input power levels as well as the accuracy of power detectors are derived from this analysis. A need for at least two different differential detector architectures is identified. Two detectors are derived from the differential power measurement concept, analyzed, and implemented in the 76-81-GHz automotive radar frequency band. They feature a low power consumption of 500 µW and, to the authors' best knowledge, the lowest published circuit areas of approximately 0.005 mm 2 while still being input matched to the differential 100 system impedance. Both these characteristics are essential to keep the overhead of the BIST minimal. With dynamic ranges of 30 dB and up to 46 dB for the two different architectures, the differential power detector concept can achieve sufficient performance for BIST applications. The robustness against process and temperature effects as well as noise is analyzed and reported for both detectors.

With automotive radar and 5G/6G communications, mass-market applications for millimeterwave circuits in silicon technologies have been identified or established in recent years. For high-volume, millimeter-wave integrated circuits, operating roughly between 30 GHz and 300 GHz, testability is a major concern, both from an overall cost as well as a quality assurance perspective. A solution for cost effective, low-overhead test of millimeter-wave integrated circuits is the integration of built-in self-test (BIST) features into the high-frequency front-end. Because BIST is an emerging topic in high-frequency circuit design, the field is still very fragmented. A plethora of different system concepts as well as building blocks have been proposed in recent years. This paper tries to provide a comprehensive overview of the state of the art in millimeter-wave BIST in an attempt to drive the field towards identification of standardized self-test solutions.INDEX TERMS Built-in self-test, CMOS, millimeter-wave transceivers, SiGe, silicon.
