TLV2771的带宽太小了，帮忙推荐一个适用于超声成像接收的前置放大器Amplifier选型和参考设计电路，需要工作带宽为0.5~20MHz，电压放大增益60dB，输入电容小于5pF。此外我还想问以下，我的输入端是压电晶体（频率几MHz），我需要的放大器设计有什么需要注意的吗，是必须要电荷放大器吗？
The bandwidth of the TLV2771 is too small, so I recommend a preamplifier Amplifier selection and reference design circuit suitable for ultrasonic imaging reception, which requires a working bandwidth of 0.5~20MHz, a voltage amplification gain of 60dB, and an input capacitance of less than 5pF. In addition, I would like to ask the following, my input is a piezoelectric crystal, is there anything I need to pay attention to in the amplifier design, is it necessary to charge the amplifier?
