@indepth_electronics: Don't have a dual power supply for analog circuits? Here's three solutions👇🏻 1⃣ If you need to power a extremely small and balanced load, two resistors will work 2⃣ If you also add two capacitors, you might be able to use this circuit to, e.g., bias an operational amplifier 3⃣ Need more current? Add complementary power BJTs, such as 2N3055/2N2955 and you're done! Have a question?
