用于自偏置低压差线性稳压器中小增益级的多重自适应电流反馈技术

Adaptive bias scheme, which can be used to provide a current proportional to the current flowing through the power transistor under high current load, avoiding the need for providing additional large fixed bias current to the circuit, has been adopted in many low-dropout regulators (LDO). When an adaptive bias scheme is applied to an LDO with a current mirror buffer, although a low chip area consu...
