Abstract

The present invention discloses a multi-purpose linear circuit module, and belongs to the basic electronic circuit of the electrical field. The module adopts the characteristic of the linear relationship between the control voltage and the output current in the complementary push-pull circuit of the field-effect tube and the characteristic of no grid current in the field-effect device, matches the peripheral auxiliary circuit, and thus realizing the linear transmission of voltage signals, the linear conversion from voltage signals to current signals, and the linear transmission of current signals. In particular, the transmission of the current signals has no relevance to the parameters of devices in the circuit, and is the real zero-distortion transmission. The circuit module is mainly used in the internal amplification circuit of the audio equipment, and can also be used in other devices which require precise transmission of electric signals. The amplifier of electric signals, which comprises the circuit module, completely has no necessary negative feedback of the loop, thus eliminating the instant intermodulation distortion of the amplifier and improving the instant hearing effects; and the circuit module provides an optimum proposal for the simulating amplification circuit.

Description

Technical field [0001] The invention relates to a multipurpose linear circuit module, which is used in an electric signal amplifying circuit, especially an audio electric signal amplifying circuit, and belongs to the basic electronic circuit in the electric field. Background technique [0002] Since the discovery of active amplifier devices, no linear devices have appeared. In order to reduce the nonlinear distortion of electrical signal amplifiers, the most widely used and most effective method at this stage is the use of loop negative feedback technology, but it can only improve distortion, not eliminate distortion. . Deep loop negative feedback will cause serious transient intermodulation distortion, which is an important reason why the sound of modern transistor amplifiers is not durable, and it is also the reason why the almost extinct tube amplifiers are revitalized. From a purely technical point of view, it is a kind of fall back. To solve this problem, it is necess...
