WebFET-Input, Low Distortion OPERATIONAL AMPLIFIER APPLICATIONS PROFESSIONAL AUDIO EQUIPMENT PCM DAC I/V CONVERTERS SPECTRAL ANALYSIS … WebContrast that with a typical MOSFET-input amplifier such as the MCP601, which is typically 29nV/sqrt(Hz), or about 700 times worse in terms of power. If you are doing audiophile audio processing, the best amplifier in the … Using the self-biased, common-source af preamplifier, which is based on a 2N4338 FET, as shown in Figure 2-3, we can get higher voltage gain than that afforded by the previous low-gain circuit. It can be noted that this circuit is identical to a common-emitter bipolar-transistor amplifier. The open circuit voltage gain … See more A simplified, common source af FET amplifier containing a 2N3819 FET is depicted in Figure 2-1. The source is grounded straight which allows this configuration suitable for af input levels below 0.6 V. When … See more Through self-biasing the FET, higher gain than what was achieved by the preceding circuit and higher output voltage can be attained. A low-gain circuit similar like this which is based on a … See more In Figure 2-4, you will see a circuit of a source follower employing a 2N4340 FET.
