Is there any circuit for generating Gaussian Noise with a mean and variance.
we should have control to change mean as well as variance accordingly.

One method is to use a very low leakage vacuum photodiode (with anode and cathode on opposite ends of the glass envelope) in a completely dark enclosure, and look at the dark current. If you have a 1 femptoamp dark current, that is equivalent to 6250 electrons per second. If you look at the number of electrons per millisecond, it should be a Poisson distribution with an average of 6.2 electrons. Increasing the current will produce Gaussian distributions. Using a light source and neutral density filters, you can get any number of electrons you want. Shot noise in solid state PIN diodes also are good sources.
