Abstract

1,079,260. Transistor testing. AMERICAN ELECTRONIC LABORATORIES Inc. Nov. 24, 1964, No. 47734/64. Heading G1U. The beta parameter (Ic/Ib) of a transistor 15 is measured by means of a meter 7 switchable between the base and collector circuits. The transistor is arranged in a common base circuit operating under Class B conditions, with a collector current below its saturation value. When the meter 7 is switched into the collector circuit, a resistor 24 is arranged in shunt with it, and the output from generator 2 is adjusted to give full scale deflection reading on the shunted meter. Switch 6 is then operated to the "beta read" position connecting the meter in the base circuit without a shunt and shorting resistor 24. The base current indicated is then a direct measure of beta. Errors are discussed and a correction curve deduced Fig. 5 (not shown).
