    • In accordance with an embodiment, an offset-compensated active load includes a pair of transistors having control electrodes connected to their drain electrodes through coupling devices. The control electrodes of the transistors are connected to each other through a plurality of charge storage elements. In accordance with another embodiment, an offset current is generated in response to coupling input terminals of an input stage together. The offset current flows towards an active load which generates an offset voltage in response to the offset current. The offset voltage is stored in the plurality of charge storage devices of the offset-compensated active load.
    • 根据实施例,偏移补偿有源负载包括一对晶体管,其具有通过耦合器件连接到其漏电极的控制电极。 晶体管的控制电极通过多个电荷存储元件相互连接。 根据另一实施例,响应于输入级的输入端耦合而产生偏移电流。 偏移电流流向有源负载,该有源负载响应于偏移电流产生偏移电压。 偏移电压存储在偏移补偿有源负载的多个电荷存储装置中。
