摘　　要：在PAC-Designer软件的支持下,在系统可编程模拟器件可非常方便地构成高输入电阻,增益在104dB范围内可精确设定、任意调整,而且带宽也能进行设计的放大器。为测量电桥的设计和制作带来了极大的便利。Supported by PAC-Designer, amplifier can be made up of programmable analog devices easily. The amplifier has following characteristics: the input resistance can be very large; the gain control can be determined accurately within 104 dB and adjusted at discretion; the bandwidth can also be designed. This facilitates the design and manufacturing of a Wheatstone Bridge.

关 键 词：ispPAC器件 电桥 增益 带宽
