Abstract
An earlier paper mentioned six operational floating amplifier (OFA) based equivalent forms of Wien-bridge oscillators (WBOs). Here, it is shown that there are, in fact, 16 such forms of WBOs. An elegant explanation of the OFA based forms is provided, thus paving the way for realizing a number of new 1-OFA oscillator configurations, i.e., from the knowledge of the conventional 1-op-amp oscillators. A novel circuit implementation of 1-OFA equivalent forms is discussed.
