This paper deals with walk-through allowing to explain the electrical response of a surface acoustic wave (SAW) resonator under inhomogeneous stress. Act of pressure on a circular membrane where is put the resonator induces inhomogeneous stress and changes the resonance frequency and the quality factor of the resonator. This paper describes a developed model allowing to explain the behavior of these...
The Symbolic Harmonic Analysis (SHA) method is a frequency domain approach for computing the steady state of ultra stable quartz crystal oscillators. First, we present a general method to convert a set of differential equations into a system of non-linear algebraic equations that can be solved for the periodic steady state solution. Then, we apply this method to simulate the behavior of a parametric...
We present a symbolic-numeric method dedicated to the simulation of ultra stable quartz, oscillators entirely in the frequency domain including the nonlinear parts of the circuit. The main idea is to replace, by symbolic computation, the nonlinear differential system describing the oscillator by a system of nonlinear equations of Fourier coefficients whose solution is an approximation of the steady-state...
