Abstract
An multi-stage error amplifier () of a power management system () is formed to insert a zero to compensate for a high frequency pole that could cause unstable outputs at some output current levels. The error amplifier () includes a feed-forward block () that isolates the capacitor () from other signal paths to facilitate low noise and high efficiency operation.
