Point Q on the load line gives us the Base current operating point of Ib = 92uA. We need to find the maximum and minimum peak swings of Base current that will result in a proportional change to the Collector current, Ic without any distortion to the input signal. As the load line cuts through equal spacings of the DC characteristics curves we can find the peak swings of Base current equally

30/06/2009 · When we choose a particular transistor for a job we look at the beta v IC graph and try to choose a transistor where the hump in the gain curve coincides with our desired collector current. This is one reason why there are some many types available....
Q 1 is the switching or control MOSFET, and Q 2 is the synchronous rectifier. L and C comprise the output filter, and R L is the load resistance. Examining a typical buck converter reveals how device requirements vary significantly depending on circuit position ( Figure 1 ).

Choose a transistor with a similar power dissipation : It is necessary to ensure that the replacement transistor can handle the power that it will dissipate within the circuit. Choosing a replacement transistor with a similar can style will often mean that both transistors have a similar power dissipation. how to add someone to your quest in eso 26/05/2010 · However, first step in the design of amplifier will be to choose the operating point for it. what should be the criterion for choice of operating point. My idea is that I use characteristic curves for the transistor i m going to use (that is 2N3904), choose a particular Q point and design the circuit for corresponding values of collector current and base current..

How To Choose A Q Point Transistor

A transistor acts as a good amplifier when it is in active region and when it is made to operate at Q-point, faithful amplification is achieved. Faithful amplification is the process of obtaining complete portions of input signal by increasing the signal strength.

  • The correct biasing point is somewhere between the fully ON or fully OFF states of the transistor. This central point is the Q-Point and if the transistor is properly biased, the Q-point will be the central operating point of the transistor. This helps the output current to increase and decrease as the input signal swings through the complete cycle.
  • Point Q on the load line gives us the Base current operating point of Ib = 92uA. We need to find the maximum and minimum peak swings of Base current that will result in a proportional change to the Collector current, Ic without any distortion to the input signal. As the load line cuts through equal spacings of the DC characteristics curves we can find the peak swings of Base current equally
