Web6 apr. 2012 · This flows through Q4 and into R4, producing an output voltage = I*R2/R1*R4, as explained. It also pulls the base of Q3 up, so that current through Q3 is approximately the same as Ic4 * R4/R3 which approximately = Ic4 if you use the same resistor values for R3 and R4. This current flows through Q2, so that Ic2 approximately = Ic1.

Web3 apr. 2024 · It is well known that a BJT’s base current iB is related to the collector current iC as iB = iC / ß, where ß is the BJT’s current gain. Typically, ß ≈ 100, though integrated-circuit BJTs may have ß ≈ 250. With reference to Figure 3a, KCL at Q1 ’s collector node implies iI = iC1 + iB1 + iB2 ≈ iC1 + 2iB1 = iC1 + 2iC1 / ß = iC1 (1 + 2/ ß ), or Web9 aug. 2024 · Traditional current limiters include resistors, low-current positive temperature coefficient thermistors, and active circuits that give minimum losses and maximum control at higher currents ...
