2-/spl mu/m, 1.6-mW gated-g/sub m/ sampler with 72 dB SFDR at 160 Ms/s and 320.25-MHz f/sub in/
The sampler is often the limitation in determining how early in the signal chain the conversion to discrete time can be done. We have fabricated a high-speed, wideband sampler based upon a charge-domain gated-gm cell that has a measured SFDR of 72 dB at 160 Ms/s and 320.25-MHz input frequency. This performance is achieved at 2% of the power and 4% of the area of a recently-released high-performance but slower sampler. Simulations indicate that far higher performance is possible in a more optimized circuit.
