This circuit, found in EDN documentation from the 90's, implements a clamp without signal deformation. The integrated circuit is from that time, uncommon nowadays.
In this oscillator a phase shift network formed by C1, C2, C3 and R1, R3, R4 determine the fase...
For inductive loads we have the configuration shown in the figure. Note that the optical coupler...
