WebOct 13, 2014 · The op must clearly have an emitter resistor given what he says for the current. Q1 is an emitter follower, so R3 is not needed. If you want to scale the design to use a higher voltage source ie 12v instead of 5 for example you would want to use PNP transistors for the high side switching and than you would need a base resistor. WebMay 22, 2024 · A good, functional model of the BJT is the simplified Ebers-Moll model shown in Figure 4.5. 1. This utilizes an ideal diode to model the base-emitter junction and a current-controlled current source located at the collector-base. This model is sufficient to achieve good analysis results with a variety of DC and low frequency circuits. on the market properties in penicuik

WebJun 11, 2015 · \$\begingroup\$ @Rimpelbekkie In the BJT it refers to current saturation, in the MOSFET it refers to voltage saturation and the names were chosen since the BJT is a current-controlled device and the MOSFET is a voltage-controlled device (to first order). It makes sense from a device physics standpoint. WebA BJT is a 3-terminal semiconductor device, as the name suggests, the term bipolar is taken from the truth that this kind of transistor includes two kinds of semiconductor materials like P-type (positive type) and n-type (negative type) where the current flows from these regions Usually, these transistors include Silicon.
