The linear CMOS oscillator circuit is shown as the chart. Just using a potentiometer RPl to make the CD4047 CMOS oscillator frequency be adjusted in the range of 1:100, and then accessing a transistor used as a variable resistor, and that is a regulator circuit with a line relationship to frequency. The emitter resistor R1 of VTl and base voltage could set the collector current. The bridge composed of diode VDl ~ VD4 ensures the symmetry work in positive and negative half-cycle.
