平衡差动电路的混合集成化A－100的前级电路采用混合集成技术集成化，图4是这片IC的内部电路框图，图5是封装前外观。这片混合集成的IC是金嗓子专有的输入电路组件。平衡输入的缓冲级和栅地－阴地互补推换电路、栅地－阴地前级激励电路以及直流同服放大器等都集成在一块60mm×3 Hybrid Integrated Balancing Differential Circuits The A-100’s front-end circuitry is integrated using a hybrid integrated technology. Figure 4 is a block diagram of the internal circuitry of this IC. Figure 5 shows the pre-packaged appearance. This mixed-integrated IC is the gold throat’s proprietary input circuit component. Balanced input buffer level and gate - ground complementary switching circuit, the ground - the ground before the excitation circuit and DC with the amplifier are integrated in a 60mm × 3
