Composite CPI amplifier

Posted on Mar 28, 2007

B is a pure output CL mode power amplifier. Preamp input portion of the circuit does not use mass conventional differential input circuit, instead of using a single-ended input

of a single-ended output Composite CPI big push to save the circuit. It works as shown in Figure 2-39, is a direct-coupled two-stage amplifier circuit amplifying ability levels even greater than the differential amplifier circuit. Circuit, REI.Rl Wei is the emitter resistance, it can be used as a negative feedback resistor to stabilize its DC working point, but also as the exchange of negative feedback resistors increase the input impedance of the circuit. And in order to pre-match. Resistance RE is used to achieve current VTi.VT2 two o
