A 115-mW, 0.5-/spl mu/m CMOS GPS receiver with wide dynamic-range active filters
This paper presents a 115-mW Global Positioning System radio receiver that is implemented in a 0.5-/spl mu/m CMOS technology. The receiver includes the complete analog signal path, comprising a low-noise amplifier, I-Q mixers, on-chip active filters, and 1-bit analog-digital converters. In addition,...

| description | This paper presents a 115-mW Global Positioning System radio receiver that is implemented in a 0.5-/spl mu/m CMOS technology. The receiver includes the complete analog signal path, comprising a low-noise amplifier, I-Q mixers, on-chip active filters, and 1-bit analog-digital converters. In addition, it includes a low-power phase-locked loop that synthesizes the first local oscillator. The receiver achieves a 2.8-dB noise figure (prelimiter), a 56-dB spurious-free dynamic range, and a 17-dB signal-to-noise ratio for a noncoherent digital back-end implementation when detecting a signal power of -130 dBm at the radio-frequency input. |
