Varactor diode test circuit
This diagram shows a practical varactor (varicap) diode test circuit, not a simulation. A DC supply provides reverse bias to the varactor through a high-value resistor, limiting current and allowing smooth voltage control. As the reverse voltage is adjusted, the junction depletion width changes, which directly varies the diode’s capacitance ...
