Other Parts Discussed in Thread:TINA-TI Hello, I have a question...How to simulate TDA2030 amplifier circuit into TINA. Thanks! Mayur, The easiest way to simulate the TDA2030 in TINA-TI would be to find a PSpice model for it and...
frequency for various R1 trims (simulation) The effect of AC matching on this differential amplifier using matched resistances, with C2 matched to C1 (10pF) results in essentially flat CM error vs. frequency (not shown). In contrast, a 10% capacitive mismatch results in a CM degradation as ...
A preconditioned signal that is applied to the input of an audio power amplifier for providing a perceived control of reactance simulation (or the Damping Factor) of the amplifier. A low frequency fundamental resonance is combined with a slowly rising high frequency preemphasis to mimic or ...

The operational amplifier is utilized for addition, subtraction, and integration of circuits, while the multiplier represents the nonlinearity of the system and connects the four state variables into a unified whole. The electronic circuit equations are obtained based on the hyperchaotic system (1) ...
4.1.1 Based on the simulation results under the 200kHz carrier and the 200kHz carrier as the simulation analysis case, the THD reaches 10% without A weighting, which can only meet the standard of entry-level power amplifier. The yellow part of the waveform line in Figure 3-2 has obvious...
A PDM 25 W Class D amplifier with GaN and Si devices as output stage is tested and compared in [79]. The test results show that when the output power is less than 20 W, the power amplifier’s distortion based on the GaN device is 0.15% lower than that of the power amplifier based...
That technique combined with the source feedback usually leads to terrible ringing for some source impedance but this amplifier has only 1dB of peaking at the worst value (around 30k). Run the LTSpice simulation to see the response curves for various values of input R (change the list as ...
