R. Urata, R. Takahashi, V. A. Sabnis, D. A. B. Miller, and J. S. Harris, "Ultrafast differential sample and hold using low-temperature-grown GaAs MSM for photonic A/D conversion," IEEE Photonics Tech. Lett. 13, 717-719 (2001)

This letter demonstrates an ultrafast sample and hold circuit using optically triggered metal-semiconductor-metal switches made of low-temperature-grown GaAs for use in a photonic analo-to-digital conversion system. A differential configuration is incorporated to reduce feedthrough noise.
