Distortion in JFET Amplifiers

چکیده

This note discusses distortion in JFET amplifiers and how to operate a JFET amplifier with low distortion. JFETs are typically used in the first stage of an amplifier where the signal amplitude is so small (microvolts up to maybe a few millivolts) that nonlinear effects are negligible. The distortion becomes significant at larger amplitudes where JFETs are not normally used–at least in open-loop applications. It is important to understand the operating conditions that separate the preferred linear from non-linear regions.

THD Analysis in Closed-Loop Analog PWM Class-D Amplifiers

In this paper, we investigate the parameters affecting Total Harmonic Distortion (THD) and Power Supply Rejection Ratio (PSRR) in PWM Class D Amplifiers (CDAs) on the basis of linear models with feedback. From our mathematical analysis, we show that the THD of a PWM Class D amplifier with feedback can be improved by increasing the gain of the integrator through adding another amplifier at the o...

New General Immittance Converter JFET Voltage-Controlled Impedances and Their Applications to Controlled Biquads Synthesis

Two new general immittance converter (GIC) JFET configurations for the realization of voltage-controlled impedances (VCI’s) are proposed. Compared with previously reported structures, the circuits exhibit wide dynamic range and low distortion properties that are frequency independent, even for nonresistive VCI’s. We consider the influence of op-amps frequency dependent gain and derive condition...

Detailed Dynamic Model for Semiconductor Optical Amplifiers and Their Crosstalk and Intermodulation Distortion

An advanced dynamic model for multisection semiconductor optical amplifiers is Presented. It accounts for the carrier and field distributions in the longitudinal direction as well as for the facet reflectivities. The model can handle arbitrary time-varying input signals and current modulations. Here the model is used to assess intermodulation distortion and crosstalk. First, cascaded amplifiers...
