    • Amplifiers with voltage and current feedback error correction are provided. In one embodiment, an amplifier includes a first input terminal, a second input terminal, an output terminal, a first stage, and a voltage feedback amplification circuit. The first stage can be used to generate first and second output currents, which can be used to control a voltage level of the output terminal. The first and second output currents can change in response to a current feedback signal and a differential input signal received between the first and second input terminals. The first stage can also generate a voltage feedback signal, which can be used by the voltage feedback amplification circuit to control a voltage level of the second input terminal based on a voltage level of the first input terminal.
    • 提供具有电压和电流反馈误差校正的放大器。 在一个实施例中,放大器包括第一输入端,第二输入端,输出端,第一级和电压反馈放大电路。 第一级可用于产生第一和第二输出电流,可用于控制输出端子的电压电平。 第一和第二输出电流可以响应于在第一和第二输入端子之间接收的电流反馈信号和差分输入信号而改变。 第一级还可以产生电压反馈信号,其可以由电压反馈放大电路使用,以基于第一输入端子的电压电平来控制第二输入端子的电压电平。
