摘要:
Four impedances are combined around an operational amplifier to give many of the characteristics of a Wheatstone bridge, but with important differences. Both the input and the output are referred to a common ground, and in some applications linearity is greatly enhanced. Stability considerations which limit the range of usable impedances are discussed.
