Question

for the silcion diodes circuit, what is the value small signal resistance (vt=26mv? select one:

Explanation:

Step1: Analyze diode state

Assume silicon - diode has a forward - voltage drop of $V_D = 0.7V$. First, find the voltage across the diode. The voltage at the anode of the diode is $V_{anode}=3V$. The voltage at the cathode of the diode is $V_{cathode}=\frac{5V\times4k\Omega}{1k\Omega + 4k\Omega}=4V$. Since $V_{anode}

Answer:

Infinity
