چکیده مقاله:
In this paper, the nonlinear analysis of the negative non-Foster capacitance is studied in the time domain and the transient response of the circuit can be used to study the stability of the circuit. For the analysis of the circuit performance, the linear time-dependent modeling approach is used. This method is based on determination of the circuit parameters at each step according to parameters of the previous steps, bias voltages and the input signal. By considering the effects of parasitic capacitors at the high frequency with applying the dynamic nonlinear model of FETs, the performance of non-foster capacitance are studied in the time domain. Results of the proposed method for analysis of non-Foster capacitor are compared with those of nonlinear analysis using commercial software which shows a good agreement together and the proposed method is validated.
