2- m, 1.6-mW Gated- Sampler with 72-dB

摘要: The sampler is often the limitation in determining how early signal chain conversion to discrete time can be done. We have fabricated a novel high-speed, wideband core based upon charge-domain gated- cell that has measured spurious free dynamic range (SFDR) of 72 dB for sample rate 160 Ms/s and an input frequency 320.25 MHz. sampling bandwidth 880 This performance achieved at 1% power area state-of-the-art track-and-hold circuit implemented much more advanced IC technology. Simulations indicate far higher possible process with minor optimization.
