Hace 4 días · Hint : Take the case of a bipolar junction transistor that uses two types of charge carriers to function. A bipolar junction transistor is an electronic device that amplifies the current that flows through the base-emitter current into the collector-emitter current with the amplification factor being beta which is defined as the ratio of the collector current to the base current.

Hace 4 días · Hint: This question can be solved with the help of the fact which is stated as the increment and decrement of the voltage gain is similar to that of the frequency and the mid-ranges of a transition amplifier gives constant voltage gain with intermediate frequency ranges. Complete step by step answer: We will consider the diagram of a transistor which is shown below.
Hace 2 días · Bell Labs is an American industrial research and scientific development company. Researchers from there are credited with the development of radio astronomy, the transistor, the laser, the photovoltaic cell, the charge-coupled device (CCD), information theory, the Unix operating system, and the programming languages B, C, C++, S, SNOBOL, AWK, AMPL, and others.
Hace 4 días · So in order to use a transistor as a rectifier, either the emitter-base segment or the collector-base segment must be used. In every transistor, the bottom is thinner than the emitter, and also the collector is lightly doped so both segments won’t work as a correct rectifier. Example: Germanium diode-connected transistor involves a drop of about.
Hace 4 días · It means its resistance can be changed. It is made up of semiconductor materials germanium and silicon. (ii)Transistors can be used as a switch in low voltage devices like LED. (iii) The transistors can be used as switches when it is cut-off or saturated regions. A transistor can be operated in three modes.
Hace 4 días · Step 1: With the help of a graph, explain the transfer characteristics of a transistor when it acts as an amplifier. An amplifier amplifies the input signal, i.e., it strengthens a weak input signal. A transistor acts as an amplifier in the active region of its output characteristics (a graph between the output voltage and the output voltage).
