WebWe can rearrange this equation to get an expression for the collector current 𝐼 sub C in terms of the quantities 𝑉 sub CC, 𝑅 sub C, and 𝑉 sub CE whose values we know. To do this, we’ll first add 𝐼 sub C times 𝑅 sub C to both sides, noting that we can then cancel the equal positive and negative terms on the right-hand side. WebThe diode D is reverse biased by V BE and the current through it is the reverse saturation current I O. Now the base current is, I B = I − I O Substituting the above value in the expression for collector current. I C = β ( I − I O) + ( 1 + β) I …
WebThe direction of current flow through the BJT is assumed for example purposes in Figure 13-1. Use either I(Q1) or I1(Q1) syntax to print the collector current. I2(Q1) refers to the base current, I3(Q1) refers to the emitter current, and I4(Q1) refers to the substrate current. Figure 13-1 – BJT Current Convention WebMay 13, 2024 · Collector Current. In CE configuration, the input current I B and the output current I C are related by the equation shown below. If …
WebVCC = IBRB + VBE Therefore, IB = (VCC - VBE)/RB For a given transistor, VBE does not vary significantly during use. As VCC is of fixed value, on selection of RB, the base current IB is fixed. Therefore this type is called fixed bias type of circuit. In the Collector circuit Apply KVL, we get VCC = ICRC + VCE Therefore, VCE = VCC - ICRC
