Abstract
PURPOSE: To avoid increment of the number of the component parts as well as to realize nonadjustment and high reliability by providing the double-terminal type resonator between the earth and one of the split electrodes of the resonator for the differential peak-type FM detector using the piezoelectric resonator.
CONSTITUTION: The common electrode of 3-terminal type double-mode piezoelectric resonator 5 is connected to one end A of the input of differential amplifier 2 with application of the FM signals. Furthermore, one side of the split electrodes of resonator 5 is connected to the other input end B of amplifier 2, and double-terminal type resonator 7 is connected between the earth and the other split electrode of resonator 5. Thus the FM detection output is obtained between the earth and output end C of amplifier 2. In such way, no adjustment is required, at the same time realizing a high output and wide band properties.
