The technological payoffs of future transistors that operate at a trillion cycles per second, or terahertz (THz), could include improved surveillance systems for detecting concealed weapons, more ...

WEST LAFAYETTE, Ind. -- A hacker can reproduce a circuit on a chip by discovering what key transistors are doing in a circuit - but not if the transistor "type" is undetectable. Purdue University ...

Not so long ago, a computer filled a whole room and radio receivers were as big as washing machines. In recent decades, electronic devices have shrunk considerably in size and this trend is expected ...

In Parts 1, 2, and 3 we took a closer look at calculating “ac” gain and how to desensitize the circuit to temperature and transistor parameter variations. In part 4 we consider the effects of a ...
