Abstract
In this paper, a narrow-band double-tuned transfer function is proposed and an LC-simulation double-tuned circuit in which its transfer function is realized with low-device sensitivity is described. Using the band pass function of a passive double-tuned circuit with mutual induction, a new double-tuned transfer function for single parameter adjustment is derived. For the basic circuit to realize the transfer function, a circuit in which negative feedback is achieved at the center frequency by RLC elements and voltage-control supplies is described, and it is shown that this circuit has low-device sensitivity in the passband. In the actual circuit configuration, the performances of the L-elements are simulated using a transistor gyrator and the coupling coefficient is adjusted by changing the value of a resistor in the resistor network. A circuit for a center frequency of 455 kHz and Q of 30 was fabricated and its coupling coefficient was adjusted by a variable resistor to evaluate the double-tuning characteristic. The calculated results were in good agreement with the experimental results. © 1997 Scripta Technica, Inc. Electron Comm Jpn Pt 2, 80(1): 69–78, 1997
