WebAnswer to Solved QUESTION 2 a) For the circuit in Figure Q2a, the WebThe characteristics of a signal point contact diode are different for both germanium and silicon types and are given as: 1. Germanium Signal Diodes – These have a low reverse resistance value giving a lower forward volt drop across the junction, typically only about 0.2 to 0.3v, but have a higher forward resistance value because of their small junction area.

WebThe forward voltage drop of a germanium diode is typically 0.3 V, compared to 0.7 V for silicon. For a germanium device, the reverse saturation current at 25°C may be around 1 μA, which is much larger than the reverse current for a silicon diode.

WebAnswer. A Germanium Diode has a voltage drop of approximately 0.3V across its leads. A diode is a device that drops a specific voltage across its terminals. It is necessary that a diode get this voltage so that the diode can conduct.
