Silicon Current Amplifier for Microampere Current Levels

摘要

A small current amplifying device (scad) utilizing what is believed to be a heretofore unused field effect transistor amplification technique is proposed. Theoretical indications and initial results on the small current amplifying capabilities of this device are promising. Unlike conventional transistors, the measured characteristics of this device show that the current gain increases as current decreases below 1 microampere input signal level. (Author)
