# Diodes

Anode Cathode

$I_D = I_{DSS}(e^{V_D/V_t} - 1)$

$V_t = \frac{kT}{q}$
where:
    k is Boltzman's constant
    T is absolute temperature
    q is electron charge


## Lab Equipment

### Low pass filter
$f_0=\frac{1}{2 \pi RC}$

## Diodes
Diode equation: $I_d = I_{DSS}(e^{\frac{V_d}{V_t}} - 1)$

$V_t = \frac{kT}{q}$
