A CMOS TIME AMPLIFIER FOR FEMTO-SECOND RESOLUTION TIMING MEASUREMENT

摘要

In this paper we present a new perspective on time amplification and its application to timing measurements on the Femto-second time scale. A simple yet practical circuit implementation for the amplification of the time between discrete (digital) events is introduced. Some metrics and figures of merit and performance are defined and parallels with the traditional amplification of "traditional physical" quantities, such as voltage and current, are drawn. The time amplifier (TAMP) has a dynamic range span from a few hundreds of Femto-seconds to a few hundreds of Pico-seconds.
