This article mainly introduces "what is the purpose of setting static work points". In daily operation, I believe that many people have doubts about the purpose of setting static work points. The editor consulted all kinds of materials and sorted out simple and easy-to-use operation methods. I hope it will be helpful for you to answer the question of "what is the purpose of setting a static work point?" Next, please follow the editor to study!

The purpose of setting the static working point is to ensure that when the amplified AC signal is added to the circuit, no matter the positive half cycle or the negative half cycle can satisfy the transistor amplification state of positive bias of emitter junction and reverse bias of collector junction.

The operating environment of this tutorial: windows7 system, Dell G3 computer.

The purpose of setting the static working point is to ensure that when the amplified AC signal is added to the circuit, no matter the positive half cycle or the negative half cycle can satisfy the transistor amplification state of positive bias of emitter junction and reverse bias of collector junction.

The static operating point refers to the transistor amplifying circuit, the static operating point of the transistor is that the AC input signal is 00:00 and the circuit is in the DC working state. The values of these currents and voltages can be expressed by a definite point on the BJT characteristic curve, which is habitually called static operating point Q.

Extended data:

The role of static work points:

Determine the static value of the voltage and current of the amplifying circuit

Selecting the appropriate static operating point can prevent the circuit from nonlinear distortion. To ensure a better magnification effect

Determination of static work points:

The static operating point is the intersection of the DC load line and some output characteristic curve of the transistor. The static operating point moves up and down the DC load line with different IB.

According to the formula Uce=Ucc-RcIc, the DC load line is drawn on the Ic/Ucc diagram, and then the transistor output characteristic curve in the case of IB is drawn, and the intersection point is the static working point.

At this point, the study on "what is the purpose of setting a static work point" is over. I hope to be able to solve everyone's doubts. The collocation of theory and practice can better help you learn, go and try it!
