Abstract
In general, the reference voltage stabilizer provides a system and method of stabilizing a reference voltage regardless of the sampling rate of a sample data system. An amplifier is utilized to amplify the reference voltage so as to maintain voltage level by stabilizing and isolating the initial reference voltage. A programmable current is utilized to modify the amplified reference voltage, thereby compensating for adjustment in current level of the reference voltage caused by system sampling. The programmable current may also be utilized to compensate for reference voltage errors occurring before amplification, by adding an intentional offset between required sink and source currents, and the current supplied by the programmable current.
