Patent ID: 8542074

Claim:
A MEMS resonator, comprising: an input port that is applied with an input voltage; an output port that outputs an output current; and N MEMS resonating units, each of the N MEMS resonating units including a vibrator and being connected to the input port and output port, and N being an integer greater than or equal to 2, wherein the N MEMS resonating units are serially connected to the input port, wherein in each of the N MEMS resonating units, the vibrator and an electrode that is opposed to the vibrator with a gap interposed therebetween form an input-side capacitance, wherein the input-side capacitance of at least one of the N MEMS resonating units is connected with an input-side capacitance of another one of the MEMS resonating units via an additional capacitive element, wherein the input-side capacitance of the at least one of the MEMS resonating units and the input-side capacitance of the other one of the MEMS resonating units are serially connected to the input port via the additional capacitive element, and wherein the additional capacitive element has capacitance higher than the input-side capacitances of the N MEMS resonating units.
