초록
This paper suggests a triple laminated piezoelectric ceramic filter composed of three piezoelectric ceramic vibrators and two sheets of thin insulator, and an equivalent circuit of the filter and several expressions for the resonant frequency; voltage, current, and power gains under the various loads and frequencies; and phase differences between the input and the output voltages are introduced and simulated from its equivalent circuit when two outputs from the side vibrators are connected in series. Those expressions show that this filter has not only a filtering function but also an amplifying function.
