“…A performance comparison of single stage amplifier and two stage amplifier shows that single stage amplifier works well at high frequency while two stage amplifier is good at mid frequency range. The study also assures that noise level is maintained low for differential amplifiers with an increases in common mode rejection ratio and power supply rejection ratio [7]. The input stage transistors affect the overall operation of a circuit at high frequencies and output transistors at low frequencies.…”

“…Yet again, the power consumption is increased due to increased area [6]. So, single stage amplifiers are the best choice to work in reduced voltage and power circuits Hernes and Sansen (2005) discuss the classification of single stage, two stage and three stage structures based on harmonic distortion. A performance comparison of single stage amplifier and two stage amplifier shows that single stage amplifier works well at high frequency while two stage amplifier is good at mid frequency range.…”

“…Further, we restrict ourselves here to consideration of such nonlinear systems (circuits), as in [3], [5], [7], [8], [12]- [20], which are only weakly (mildly) nonlinear. And, it is worth noting at this point that this class of systems has been defined in the literature cited above using different approaches and formulations.…”

Abstract-This paper deals with an extension of the Rosenstark's linear model of an amplifier to a nonlinear one for the purpose of performing nonlinear distortion analysis. Contrary to an approach using phasors, our method uses the Volterra series. Relying upon the linear model mentioned above, we define first a set of the so-called amplifier's constitutive equations in an operator form. Then, we expand operators using the Volterra series truncated to the first three components. This leads to getting two representations in the time domain, called in-network and inputoutput type descriptions of an amplifier. Afterwards, both of these representations are transferred into the multi-frequency domains. Their usefulness in calculations of any nonlinear distortion measure as, for example, harmonic, intermodulation, and/or cross-modulation distortion is demonstrated. Moreover, we show that they allow a simple calculation of the so-called nonlinear transfer functions in any topology as, for example, of cascade and feedback structures and their combinations occurring in single-, two-, and three-stage amplifiers. Examples of such calculations are given. Finally in this paper, we comment on usage of such notions as nonlinear signals, intermodulation nonlinearity, and on identification of transfer function poles and zeros lying on the frequency axis with related real-valued frequencies.

“…However, due to the difficulty to generate analytical expressions in circuits with hard-distortion and at high-frequencies , the distortion analysis is generally performed for weakly nonlinear circuits (Li & Pileggi, 2005). In this case, the application of symbolic analysis for behavioral model generation is suitable for the distortion analysis in single-, two-and three-stage amplifiers (Hernes & Sansen, 2005). Combinations of symbolic methods with numerical analysis for nonlinear circuits are presented in (Daems et al, 2002;Manthe et al, 2003).…”
