WebAug 16, 2024 · In the saturated region, our bipolar junction transistor works as a switch, an ON switch, and the collector current is fairly equal to the emitter current. ... If you can … WebAug 22, 2015 · You can move the clamping transistor (call it Q1) "down" by connecting the transistor emitter to DC supply V-. You must now provide a means of driving the base high relative to V-. This would usually take 2 transistors to do but a "clever" circuit. is to use a PNP transistor Q2. Connect Q1 base to V- with say 100k.

WebSep 7, 2024 · The circuit is similar to that of the Common Emitter circuit. The difference is that we need to turn the transistor fully ON (saturated) or fully OFF (cut-off) to be able to operate it as a switch. An ideal transistor switch has infinite resistance between the Emitter and the Collector when it is turned fully-OFF leading to 0 current flow ... WebFeb 22, 2024 · When a BJT is connected across the load resistance R L in CE mode configuration it can be operated as a switch. The BJT behaves like an open switch when it is biased in cutoff region and it behaves like a closed switch when it is …
