摘要
A differential amplifier power supply is derived from the same source that generates the reference voltage for the differential amplifiers. This will ensure the direction of voltage level shifts of these two voltages to be in tandem. That is, these two voltages will move in the same direction due to any variations in the source since they are generated from the same regulator. In this way receiver timing errors can be significantly reduced in source synchronous and common clock interfaces.
