Monitoring Architecture for a 76-81GHz Radar Front End

Built-In Self-Test of Millimeter-Wave Integrated Front-End Circuits: How Far Have We Come?

“…The loopback path and attenuator are integrated into the front-end antenna duplexer which is described in detail in [46]. Another loopback architecture, targeted at automotive radar, is presented in [47]. It implements two loopback paths: one before, the other after the PA.…”

“…It has been implemented up to very high frequencies, e.g. [1], [47], [67]- [70]. Usually, the coupler has to be co-designed with the PA to ensure that the optimum output impedance of the amplifier is not impacted.…”

Differential-Mode Power Detection for Built-In Self-Test of SiGe Automotive Radar Transceiver Front Ends

“…The first example, Fig. 1(a), is a configuration often found at transmitter outputs to measure the output power of the power amplifier (PA), e.g., [25], [26], [27], [28]. A directional coupler is placed between the output of the PA and the antenna.…”

“…In contrast to the other two approaches, the power at the detector input is higher than at the CUT. Both dedicated test signal generators [26] as well as loopback from the transmitter output [27] have been used in practice to generate the test signal.…”

E‐band power detector with robust temperature performance in 130 nm SiGe BiCMOS

“…Introduction: High-performance multi-channel transceiver systems at E-band integrated with built-in-self-test (BIST) functions have been demonstrated in SiGe BiCMOS [1,2] and CMOS technologies [3] recently. Variety of BIST functions have been developed, from power detectors (PDs), lock-detectors for PLLs to voltage monitors for internal voltages etc.…”
