As improved, input buffer circuitry comprises a pull up stage to pull up the voltage of the differential amplifier output slightly higher during an output low condition.
作为改进，输入缓冲电路组成的阶段拉一拉期间的输出低的条件差分放大器的输出电压略高。

The technique transfers the offset voltage from the output to other parts of the differential amplifier and can greatly reduce the input-referred offset voltage without extra power consumption.
The parts have a standard voltageinput, which together with the differential reference input allows easy interface to an external temperature sensor, such as an RTD, thermistor, or diode.
