The Voltage Amplification Stage (VAS) serves as a critical architectural bridge in amplifier design, positioned between the input pair and the power output section. Its primary function is to build the voltage swing required before power can be delivered to the load. The VAS significantly influences key amplifier characteristics including voltage swing capability, linearity, compensation behavior, speed, and control handedness to subsequent stages. This stage ensures that the signal is properly amplified in voltage before being passed to the driver and output sections, enabling the amplifier to drive loads with authority and precision.
