The application range of field-effect transistors in audio digitization is becoming increasingly wide
Finally, the author can only select two tubes with an error of 3.8% from K389 as single-sided differential input stages (in the past
It is well known that the loss of MOS transistor output stage is greater than that of bipolar transistor.
As mentioned earlier, increasing the power supply voltage by only about ± 5V under the same circuit conditions does not enable the MOS power output stage to achieve the same power as bipolar transistors.
In fact, compared with bipolar transistors, MOS transistors have excellent high-frequency characteristics and distortion mainly caused by even harmonics.
To achieve the same output power as a bipolar transistor in the same circuit
