A high performance all digital PLL RF synthesizer is presented. The key building block is a high resolution time to digital converter (TDC) that allows for low in-band phase noise. The TDC uses a novel architecture that combines a simple analog circuitry with a digital control loop to achieve a PVT stable sub-gate delay quantization step, with small area and low power consumption. A prototype of the...
A complete analog front-end, with the exclusion of the frequency synthesizer, for FM broadcasting occupies 2.8 mm2 active area in a standard 0.35 mum CMOS technology. The use of current driven passive mixer and switch capacitor polyphase filter gives +100 dBmuV IIP3, 52 dB adjacent channel selectivity and +39 dB image rejection without trimming or tuning. The output noise is 390 nVparradic(Hz), with...
A 35mW- 3.6mm2GPS radio has been integrated in a 0.18µm CMOS process. Housed in a standard VFQFPN52 package, the GPS radio needs just a few external passive components for the input matching network and one external reference for the Synthesizer. The GPS receiver chain down-converts a Coarse/Acquisitions L1 signal with NF-5.3dB, conversion gain 81dB, Image Reject > 32dB. The synthesizer features...
