用于片上补偿和软启动功能的双路径误差放大器与电容倍增器技术

Techniques of a dual-path error amplifier and two capacitor multipliers for providing on-chip frequency compensation and soft-start function are proposed in this paper. The concept of the dual-path error amplifier is to use two currents to charge and discharge a compensation capacitor simultaneously. As a result, the equivalent capacitance is enlarged significantly with little additional power and...
