Harmonic distortion in power amplifiers are mainly caused by the non linearities of the active elements (transistors). The active element used for amplification whether BJT, FET, MOSFET or anything like that may not equally amplify every points in the input waveform and this is the reason behind ...
The slope at low power indicates (5.2±0.4) Â 10 À 5 mW À 1 normalized conversion efficiency; however the curve rolls off because of distortion of the resonance. 3 2 1 0 –1 –2 –3 –2 0 2 x coordinate (microns) 3 2 1 0 –1 –2 –3 –2 0 2 x coordinate (microns...
power switch, the second switch being configured to be cycled on and off responsive to a switching signal voltage such that the second switch is turned on before the power switch is turned off and such that the second switch is turned off after a current through the power switch is ...
We investigate the influence of two important practical design parameters on total harmonic distortion (THD) for the design of low-voltage (0.9-1.4 V) low-power analog Class-D amplifiers: the linearity of the carrier waveform and the impedance of the output stage. We show that the carrier non...
18.The Doherty power amplifying apparatus of claim 8, wherein the carrier amplifier and the peaking amplifiers are arranged such that nonlinear characteristics therebetween are canceled. 19.The Doherty power amplifier of claim 8, wherein the harmonic control circuit is arranged in front of each of...
A method and system is described wherein a signal with a lower frequency is up-converted to a higher frequency. In one embodiment, the higher frequency signal is used as a stable fr
Consequently, there is no harmonic distortion associated with error terms that are constant with respect to time. The transfer functions shown in Equation 2 and Figure 2 are those of the entire data-acquisition system; they include the effect of the voltage reference, ADC and other system ...
Harmonic balance is a frequency-domain analysis technique for simulating distortion in nonlinear circuits and systems. It is well-suited for simulating analog RF and microwave problems, since these are most naturally handled in the frequency domain. You can analyze power amplifiers, frequency multipliers...
