Hi guys,
When we calculate noise, there are two kinds of equivalent model: noise voltage and noise current. However, it confused me when I analysis the circuit below.
When I use noise current way to analysis the circuit, noise current flows to the ground not through resistor. However, when I use noise voltage way, the noise current flows through resistor. Therefore, the resistor will consume power. But there are not independant sources providing power. It violates conservation of energy. What's wrong with noise voltage way?

Ming
