There are equivalent P-channel devices, just as there are PNP and NPN bipolar transistors ... effect less coupled to small signal work. Where a bipolar transistor requires significant base ...

The transistors being made by Bell just didn't work the same way twice, and on top of that, they were noisy. While one lab at Bell was trying to improve those first type-A transistors, William ...

Many people giving talks had complained about the current germanium transistors -- they had a bad habit of not working at high temperatures. Silicon, since it's right above germanium on the ...
