    • An apparatus includes an input difference determination circuit configured to determine a digital value based on a difference between first and second input signals, and a charge pump configured to provide a supply voltage to the first and second transistors to determine the digital value. The input difference determination circuit includes a first transistor and a second transistor cross-coupled to each other. A method includes generating a voltage using a charge pump, providing the voltage to an input difference determination circuit, and determining a digital value based on a difference between first and second input signals by the input difference determination circuit.
    • 一种装置包括:输入差分确定电路,被配置为基于第一和第二输入信号之间的差异确定数字值;以及电荷泵,被配置为向第一和第二晶体管提供电源电压以确定数字值。 输入差分确定电路包括彼此交叉耦合的第一晶体管和第二晶体管。 一种方法包括使用电荷泵产生电压,向输入差分确定电路提供电压,以及通过输入差分确定电路基于第一和第二输入信号之间的差确定数字值。
