摘要:
Embodiments of the present invention provide an approach for utilizing a sense amplifier to select a suitable circuit, wherein a suitable circuit generates a voltage that is greater than or equal to a configurable reference voltage. An amplifier gain selector selects a voltage gain of a sense amplifier having input terminals, auxiliary inputs, an output, an array of resistive loads, and the amplifier gain selector. Auxiliary inputs are utilized to nullify direct current (DC) offset voltage of the sense amplifier. Combinatorial logic circuitry connects the input terminals of the sense amplifier to output terminals of a circuit that is within a group of circuits. A comparator circuit determines if the circuit generates a voltage greater than or equal to a configurable reference voltage, based on the output of the sense amplifier.

本发明的实施例提供了一种利用读出放大器来选择合适电路的方法,其中合适的电路产生大于或等于可配置参考电压的电压。 放大器增益选择器选择具有输入端,辅助输入,输出,电阻性负载阵列和放大器增益选择器的读出放大器的电压增益。 辅助输入用于消除读出放大器的直流(DC)偏移电压。 组合逻辑电路将读出放大器的输入端连接到一组电路内的电路的输出端。 比较器电路基于读出放大器的输出来确定电路是否产生大于或等于可配置参考电压的电压。
