Proportional Compensated Buck Converter With a Differential-In Differential-Out (DIDO) Error Amplifier and Load Regulation Enhancement (LRE) Mechanism

A differential-in differential-out error amplifier and a load regulation enhancement mechanism are proposed in the buck converter that aims to improve load regulation and noise immunity. By using the proportional compensator in the proposed converter, there is no need of external compensation components in this design. As a result, a compact-size and high-performance dc-dc buck converter can be guaranteed. Experimental results show that load regulation can be improved from 0.5 to 0.025 mV/mA. The test chip was fabricated by 0.25 μm CMOS process and occupied 1.65 mm active silicon area.
