Voltage And Current Noise Tester Circuit



This is a simple design circuit for tester circuit. This circuit is based on LM791. This is the figure of the circuit.


Using large resistor value make the current noise dominate since it is coupled into the resistance and thus voltage noise and thermal noise become negligible compared to the current noise. The output voltage is specified as Vout and input voltage as Vin and box noise enabled is checked.
