The multi-tanh circuit as a triwave-to-sine converter
W.A. Evans, Jamie Williams · IEE Journal on Electronic Circuits and Systems · 1979
The paper describes the operation of the multi-tanh circuit as it applies to triangle-to-sine conversion. The treatment includes a detailed examination of the properties of the transfer function of the circuit, an evaluation of total harmonic distortion with circuit parameters chosen to minimise total harmonic distortion.
