The so-called forward-bias i-v relationship for a silicon diode is:
where
wherek is Boltzmann’s constant, T is absolute temperature in kelvins, and q is the charge of an electron. Consider the circuit shown in Figure P3.83. KVL applied around the loop results in a transcendental equation for the loop current
