Multiple choice

A silicon PN junction is forward biased with a constant current at room temperature. When the temperature is increased by 10oC, the forward bias voltage across the PN junction

  1. increases by 60mV

  2. decreases by 60mV

  3. increases by 25mV

  4. decreases by 25mV

D Correct answer
Explanation

For every $1^\circ C$ increase in temperature, forward bias voltage across diode decreases by $2.5 mV$. Thus for $10^\circ C$ increase, there us $25mV$ decreases.
