Abstract

PURPOSE: To avoid increment of the number of the component parts as well as to realize nonadjustment and high reliability for the differential peak-type FM detector using the piezoelectric resonator by installing the 3-terminal type double-mode piezoelectric resonator between the earth and one of the split electrodes of the 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 split electrodes of resonator 5 is connected to the other input end B of amplifier 2, and optional two terminals of 3-terminal type double-mode piezoelectric resonator 7 are connected between the earth and the other split electrode of resonator 5. And the FM detection output is obtained between the earth and output end C of amplifier 2. Thus no adjustment is required, at the same time realizing a high output and wide band properties.
