    • A reception circuit disposed within an ultrasound probe is provided. The reception circuit includes, at least one amplifying unit configured to amplify echo signals received by ultrasound transducers, and at least one delay unit connected to the amplifying unit and including a first circuit and a second circuit each configured to apply a delay time to an output from the amplifying unit, wherein the first and second circuits each have a plurality of capacitor banks. Each capacitor bank includes two or more capacitors each configured to write therein a signal amplified by the amplifying unit, wherein the two or more capacitors are different from one another in capacitance, write switches configured to write an output current into the first and second capacitors of the two or more capacitors, and read switches configured to read the output written into the first and second capacitors.
    • 设置在超声波探头内的接收电路。 接收电路包括:至少一个放大单元,被配置为放大由超声换能器接收的回波信号;以及至少一个延迟单元,连接到放大单元,并且包括第一电路和第二电路,每个被配置为向输出端施加延迟时间 其中所述第一和第二电路各自具有多个电容器组。 每个电容器组包括两个或更多个电容器,每个电容器被配置为在其中写入由放大单元放大的信号,其中两个或更多个电容器在电容中彼此不同,配置为将输出电流写入第一和第二电容器 两个或更多个电容器和被配置为读取写入第一和第二电容器的输出的读取开关。
