Description
Summary:This paper presents a reconfigurable mixed-signal-processing circuit for high-speed pulse compression radar (PCR). Mixed-signal design techniques incorporate calibration and adaptation to improve the performance of a PCR receiver. Adaptive bandwidth PCR is an important feature for maximizing the dynamic range of a low-power radar system. The baseband signal processor includes a variable gain amplifier, 4-bit digital-to-analog converter, high-speed analog correlator, passive integrator, a 4-bit flash analog-to-digital converter, and a multi-range delay-locked loop. This proposed system is fabricated in 90-nm CMOS and can be configured to work from 50 Mb/s to 1 Gb/s with 2/3/5/7-bit Barker codes. The proposed calibration techniques improve the sidelobe reduction to 15.6 dB at 1 Gb/s. The total power consumption is 42 mW at the peak rate of 1 Gb/s for 15-cm range resolution.
