摘要：本发明公开了一种鲁棒的微机械谐振器的运动信号提取方法，本发明通过上边带同相解调、上边带正交解调、下边带同相解调和下边带正交解调可以得到上边带幅度、上边带相位、下边带幅度和下边带相位，谐振器的谐振幅度信号为上边带幅度与下边带幅度之和的二分之一，谐振器的谐振相位信号为下边带相位与上边带相位之差的二分之一，从而可以消除环境因素和驱动频率对接口电路的幅度增益和相位滞后造成的影响，实现对环境的鲁棒性。本发明原理简单，能应用于微机械谐振器的运动信号提取，如微机械陀螺。

摘要： Embodiments of the invention include delay line circuitry that is integrated with an organic substrate. Organic dielectric material and a plurality of conductive layers form the organic substrate. The delay line circuitry includes a piezoelectric transducer to receive a guided electromagnetic wave signal and to generate an acoustic wave signal to be transmitted with an acoustic transmission medium. An acoustic reflector is communicatively coupled to the acoustic transmission medium. The acoustic reflector receives a plurality of acoustic wave signals from the acoustic transmission medium and reflects acoustic wave signals to the piezoelectric transducer using the acoustic transmission medium. The transducer converts the reflected acoustic signals into electromagnetic waves which are then transmitted back through the antenna and decoded by the reader.

摘要： A reconfigurable circuit and a related method for its use, the circuit including multiple microelectromechanical systems (MEMS) switches connected between selected points in the circuit. The MEMS switches are controlled to select a desired circuit condition, such as an impedance matching condition, and then the switch conditions may be fused permanently. In the context of an impedance matching circuit, the MEMS switches may be used to optimize matching after circuit fabrication or after packaging, thereby allowing optimization even after potentially performance changing events.

摘要： Comb filter having a comb like band pass characteristic curve by using an ultrasonic delay line (9) is improved to reduce its size. An input signal is given through an impedance element 13 to a single terminal 10a of an improved delay line 9, wherein the single terminal serves as the input terminal and at the same time as the output terminal. Signals at both ends of the impedance element 13 are given to a mixing circuit 15 for summing or substracting thereby. In the improved delay line 9, the ultrasonic wave radiated from the input terminal travels twice the conventional delay line and comes back to the original terminal, and thereby a sufficient propagation distance is obtainable in a small delay line.
