TRANSFORMER CONDUCTANCE AMPLIFIER CIRCUITPROBLEM TO BE SOLVED: To realize an active filter in which both distortion and S/N performance can be stabilized by enlarging an input dynamic range without compressing the signal.FURUYAMA KENJI古山 健志...
A transformer coupled amplifier circuit that eliminates transformer induced non-linearities by way of a dual feedback path without sacrificing any of the inherent attributes of general transformer cou
The circuit presented here is an unbalanced-to-balanced converter that can be used to drive audio transmission lines. In the past, a line amplifier coupled with a 600 惟 / 600 惟 transformer was used for this. The galvanic isolation was ... T Clinquart - 《Elektor》 被引量: 0发表: 20...
The benefit here is that, unlike an amplifier, a transformer generates essentially no noise. However, the parasitics in a 1:2 or 1:4 transformer are much more difficult to compensate for, particularly over a wide range of frequencies. With a 1:2 turns ratio, for example, the capacitive ...
Figure 13.9.Leak 25 Plus amplifier An alternative arrangement, which used a similar technique to combine part of the cathode circuit in theoutput transformer, was developed by Quad and the circuit of the classic Quad 2 is given inFigure 13.10. ...
Figure 1. For resistor values less than 20MΩ, this simple transimpedance amplifier is acceptable for use with some current sources. Resistor values above 20MΩ are notoriously difficult to apply. For applications requiring a transimpedance above 20MΩ, consider the circuit of Figure 2. The outpu...
Sean Gold, William Jett, in Analog Circuit Design, Volume Three, 2015 Driving transformer-coupled loads Transformer coupling is frequently used to step up transmission line signals. Voltage signals amplified in this way are not constrained by local supply voltages, so the amplifier’s rated current...
