Hybrid Power Amplifier 03

The unit structure of CD4069 is shown in Figure 2-5(a). It is composed of two CMOS FET butt surfaces, and its input-output
characteristics are shown in Figure 2-s(b). Because its unit characteristic is an excellent switching curve, CD406q is often combined into
automatic switches, single spikes or square wave generators for various control circuits, and is rarely used for linear amplification. 6 In fact, Figure 2-5(b) The curve shown is an idealized characteristic, and its actual characteristic curve is shown in Figure 2-5(c). There is a linear area
in its middle area . If a unit of CD4069 is connected to the amplifier form shown in Figure 2-5 (d), then when the audio signal ei is injected into the input terminal of CD4069 , the amplified high-fidelity signal eo can be obtained at its output terminal.
