Abstract :
This paper shows how to measure capacitance by measuring thermal noise. The goal is to design a circuit in which noise voltage is large enough to measure while remaining a simple function of capacitance. Furthermore, the bandwidth of the noise must be appropriate for measurement by a multimeter.
