WebDec 6, 2024 · At the transmitting frequency C1 has so low reactance (about 1,6 ohms at 100MHz) that you can think the base being grounded and that's needed to make the oscillator to work. It's very common in electronics that the same circuit work totally differently in different frequencies at the same time. WebJan 9, 2024 · In a BJT (Bipolar Junction Transistor), say NPN in common base configuration, we forward bias the Base-Emitter Junction and reverse bias the Base-Collector Junction when using a constant DC supply. Intuitively, when I replace DC with AC, the polarity changes after every half cycle.
