A non-statistical approach to tolerance analysis of microwave circuits

In this contribution, a method to compute tolerances of microwave circuits is presented. This non-statistical approach is based upon sensitivity analysis which provides the coefficients of the Taylor series expansion of the performance of interest. The method applies to any traditional electronic circuit performances (like gain as ratio, gain in dB, input/output impedance), as well as to specific microwave performances (transducer gain, input/output reflection coefficients, input/output VSWR, S parameters, etc...).
