摘要:

It is shown that a negative resistance of a definite value, introduced into the plate circuit of a thermionic valve theoretically allows the voltage sensitivity to become infinite. Practical application is made to construct high sensitivity direct‐current amplifiers. The data show a mutual conductance of 30,000 microamp. per volt.
