Abstract
Embodiments of the invention relate to a reference voltage pre-processing circuit and method for a reference voltage buffer. The embodiments include a filter to control/reduce the noise and/or interference attached to a reference voltage to be provided to a reference voltage buffer by passing the reference voltage via two transistor in series. Furthermore, the embodiments include an auxiliary voltage circuit which interfaces the filter and the reference voltage buffer to avoid that the reference voltage buffer get an invalid reference voltage.
