Bjt amplifier lab manual

The basic BJT amplifier circuit like the one shown in Figure can be de signed to exhibit various desirable characteristics. An impor tant decision involved in designing this. BIPOLAR JUNCTION TRANSISTOR (BJT) Figure Symbols for BJTs. Basic Concepts The operation of the BJT is based on the principles of the pn junction. As indicated in Figure , there are two basic types: (a) the npn and (b) the pnp. In the npn, electrons are injected from the forward-biased emitter into the thin base region where, as.
