A Bipolar Junction Transistor is a solid-state device in which the current flow between two terminals (the collector and the emitter) is controlled by the amount of current that flows through a third terminal (the base).
A Bipolar Junction Transistor can be used for analog circuits, especially for very-high-frequency applications, such as radio-frequency circuits for wireless systems. Bipolar transistors can be combined with MOSFETs in an integrated circuit by using a BiCMOS process to create innovative circuits that take advantage of the best characteristics of both types of transistor.

Rb = Base Resistance
Vin = Input Voltage
Rc = Collector Resistance
Re = Emitter Resistance
Vs = Supply Voltage
Vc = Collector Voltage
Ve = Emitter Voltage
Vb = Base Voltage

Ic = Collector gain x Ib
Ve = IC x Re
Vb = Ve x Base to Emitter Drop
Vc = Vs - IC x Rc
If (Vc < Ve) then,

Vc = Ve
Vb = Ve + Base to Emitter Drop
