| Abstract: | Because the original varindor circuit and the 1 kHz oscillator of 521 Dual Induction-Spherically Focused Logging Tool consist of isolate circuit elements connected by wires, the interference among the wires affects the processing of the measured signal. Using an integrated CMOS chip to re place the isolated components in the 1 kHz OSC circuit improves the signal stability of the spherically focused logging tool. The interference is further reduced and the reliability is improved by making the varindor circuit onto a printed circuit. The detailed procedure of debugging the varindor circuit is described and the application success after these two modifications is Dresented. |
