Abstract :
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 analog-to-digital conversion system. A differential configuration is incorporated to reduce feedthrough noise.
