Abstract
An electrical circuit having an oscillator and additional structural elements that are connected to the oscillator. In an iterative method, upon variation of circuit parameters of the additional structural elements, the following steps are carried out for each instance of the circuit parameters: a stability analysis of the circuit is carried out for each respective instance, and if the circuit oscillates, a first value is assigned to the instance in a matrix in which all the instances being examined are stored. Otherwise, a second value is assigned to the instance in the matrix.
Claims10
A method for determining an oscillating region of an electrical circuit comprising at least one oscillator and additional structural elements connected to the oscillator, the method comprising the steps of:
- in a computing device, executing, in an iterative method, upon variation of combinations of circuit parameters of the additional structural elements, the following steps for each instance of the circuit parameters:
- performing a stability analysis of said electrical circuit for a respective instance for determining whether said instance oscillates;
- if the analyzed instance oscillates, assigning said instance a first value in a matrix in which all parameter combinations being analyzed are stored, said first value indicating that said instance oscillates;
- if the analyzed instance does not oscillate, assigning said instance a second value in the matrix, said second value indicating that said instance does not oscillate;
- and
- deriving the oscillating region from said parameter combinations that have been assigned said first value in said matrix.
