Abstract

PURPOSE: To unify the resonator connecting terminal, by connecting a plurality of inverting amplifiers in series, and feeding back the output of inverting amplifiers at an even and odd number of stages to the input of the inverting amplifier at the 1st stage via a capacitor and a resistor.
CONSTITUTION: The input of an inverting amplifier I21 is connected to external terminal and the input and output of the amplifier I21 is connected with a resistive element R24. The output of the amplifier I21 is connected to the input of an inverting amplifier I22, and the output of the amplifier I22 is connected to the input of the amplifier I21 via a capacitor C22. Thus, a feedback circuit is constituted. As a result, the resistor R24 and the capacitor C22 can be included in an integrated circuit, only one external terminal is enough, and an arbitrary oscillating frequency is obtained by connecting an LC resonance circuit externally only.
