    • An apparatus, a method, and a system are provided to calibrate an offset in an amplifier. The apparatus can include an amplifier, a voltage control unit, a comparator, and a processing unit. The amplifier can have four terminals: a positive differential input (VIN+), a negative differential input (VIN−), a positive differential output (VOUT+), and a negative differential output (VOUT−). The voltage control unit can be configured to adjust a first voltage on VOUT+ and a second voltage on VOUT−. The comparator can be configured to compare the first voltage on VOUT+ to the second voltage on VOUT− when VIN+ and VIN− are coupled to a common voltage. Further, the processing unit can be configured to provide a control signal to the voltage control unit based on the comparison of the first and second voltages on VOUT+ and VOUT−, respectively.
    • 提供了一种装置,方法和系统来校准放大器中的偏移。 该装置可以包括放大器,电压控制单元,比较器和处理单元。 放大器可以有四个端子:正差分输入(VIN +),负差分输入(VIN-),正差分输出(VOUT +)和负差分输出(VOUT-))。 电压控制单元可配置为调节VOUT +上的第一电压和VOUT-上的第二电压。 当VIN +和VIN-耦合到公共电压时,比较器可以配置为将VOUT +上的第一个电压与VOUT-上的第二个电压进行比较。 此外,处理单元可以被配置为基于VOUT +和VOUT-上的第一和第二电压的比较来向电压控制单元提供控制信号。
