Wien_bridge_oscillator_with_common_mode_suppression

Figure 4-39 shows another version of the Fig. 4-34 circuit, but with automatic trim and common-mode suppression (similar to that of Fig. 4-28). The circuit output (trace A, Fig. 4-40) contains less than 0.0003% (3 ppm) distortion (trace B), with no visible correlation to gain-loop ripple residue (trace C). This level of distortion is below the uncertainty floor of most distortion analyzers. LINEAR TECHNOLOGY, APPLICATION NOTE 43, P. 32, 33.
