摘要： In a high-performance interface circuit for micro-electromechanical (MEMS) inertial sensors, an excitation signal (used to detect capacitance variation) is used to control the value of an actuation signal bit stream to allow the dynamic range of both actuation and detection paths to be maximized and to prevent folding of high frequency components of the actuation bit stream due to mixing with the excitation signal. In another aspect, the effects of coupling between actuation signals and detection signals may be overcome by performing a disable/reset of at least one of and preferably both of the detection circuitry and the MEMS detection electrodes during actuation signal transitions. In a still further aspect, to get a demodulated signal to have a low DC component, fine phase adjustment may be achieved by configuring filters within the sense and drive paths to have slightly different center frequencies and hence slightly different delays.

摘要： A novel out-phasing-array transmitter system and method are disclosed. The method is based on decomposing the input signal into an array of signals to drive a general, multiple paths out-phasing-array transmitter. This decomposition is less sensitive to the phase difference between the multiple paths, and extends the dynamic range of the out-phasing-array transmitter system. The wide dynamic range and the multiple transmission paths increase the maximum achievable output power, in accordance with the WiMAX specifications.

摘要： Embodiments include systems and methods for fine control of beam steering for wide band wireless applications using a phased array of antenna elements. In one embodiment, a digitally controlled delay line delays the signal output from a modulator in each branch of multiple branches feeding multiple antennas in an array. An output of the digital delay line is input to a digital to analog converter. A second digital delay line also delays the signal within the digital to analog converter. The manner of implementation of the delays enables accurate production of a steered beam at a high data rate.
