摘要：
In an embodiment, an apparatus may include an amplifier circuit including a first input to receive a signal, a second input to receive a feedback signal, and an output. The apparatus may further include a buffer circuit including an input coupled to the output of the amplifier and including an output coupled to an output node. The apparatus may also include a feedback circuit coupled between the output node and the second input of the amplifier circuit. The feedback circuit may include at least one non-linear resistor configured to define a feedback ratio that changes in response to a voltage at the output node.
