“…Sueh methods, while they provide useful analytical insight into the operation of the circuit, are typically very complex for practical applications [8], [9]. The other class of methods are simulation based and consist of algorithms that are employed by simulators to try and measure distortion in the most efficient way possible.…”

“…To prove that the parameters in the moment vectors are equivalent to the numerical computation of Volterra kernels we start by writing the Volterra Series representation of a nonlinear system with memory, which is given by The Volterra Series expression in (4.37) is similar to the expression shown in (4.29) which proves that the proposed method is essentially the numerical computation of the Volterra operators. In a similar fashion to memoryless systems, the location of the parameters to compute the value of IP3 are the entries in bold found in the moment vectors at the locations shown in Table 4.2 [9], [41]. For the case of memoryless systems, the expressions for these kemels simplify to the terms k 1 and k3 in …”

“…However, such methods are practically unusable except for very specifie cases. This is due to the fact that the computation of the Volterra kernels requires complex analytical manipulations which are extremely difficult to perform except for very simple circuits and are impossible to automate [8], [9].…”

State-space modeling of fully differential Gm-C filters with weak nonlinearities is used to develop a fast algorithm for intermodulation distortion estimation. It results in simple analytic formulas that apply directly to Gm-C filters of any order and any fully balanced topology. The algorithm has been verified using SpectreS (SPICE) and Simulink simulation. Theory and simulation results are found in good agreement.

A very low voltage transconductor for video frequency range applications and compatible with standard CMOS technology is described. In the proposed transconductor, except the DC level shifter circuit (DCLS), the whole transconductor uses the main supply voltage [which can be as low as 1.5 V in a standard 0.6 µm CMOS technology] while the DCLS uses a simple charge-pump circuit as its supply voltage and has a very low current consumption. In addition, proper common-mode sense and charge-pump circuits are developed for this low-voltage application. Meanwhile, some techniques to improve the frequency response, linearity, and noise performance of the proposed transconductor are described.In a standard 0.6 µm CMOS technology and single 1.5 V supply, simulations show that the proposed transconductor futures a THD of −50 dB for 1.4 V pp and 10 MHz input signal and −60 dB for 1.4 V pp and 1 MHz signal where the threshold voltage of MOS transistors could be as high as 1 V. Based on the proposed transconductor, a lowpass filter with 700 kHz to 8 MHz programmable cutoff frequency and a bandpass 10.7 MHz second order filter were implemented.
