What are the differences between a (pnp) and a (npn) Bipolar Junction Transistor?
An NPN bipolar junction transistor (BJT) is used to turn on and off a 30 Ohm load using an Arduino digital output pin as shown. Assuming the transistor is on, in the saturation region, determine the power delivered to the 30 Ohm load. The voltage drop across the collector-emitter junction of the transistor is 0.2 Volts. +5 v 1308 ARDUINO SV UNO mne гоо са Vce=0.2 v Saturation VBE = 0.7V in active & Saturation regions

Consider a silicon device (which happens to be an npn bipolar transistor) with an emitter doping of 10^17/cm3, a base doping of 8x10^15/cm3 and a collector doping of 2x10^15/cm3. Carefully calculate how the band diagram, charge density, electric field and electrostatic potential as a function of distance for this device changes from the equilibrium case when this bipolar transistor is properly biased to work as an amplifier. In other words, show how the band diagram changes when the emitter-base junction...
A. As an electronic device, what is the function or purpose of a bipolar junction transistor when it is utilized in an analog circuit? B. Make a sketch of a typical volume element of a silicon pnp transistor connected in active larger than the base current. In your sketch, show the path of carriers (both holes and electrons) as they proceed from the emitter to the collector. Identify the paths of all 3 types of base current and explain what...
