11.4. DC Stabilization with the Feedback Resistor

The dc output voltage can be set close to zero with negative feedback for normal operation as a linear amplifier as illustrated in Fig. 11.7. A portion of the output voltage is applied back to the input as the voltage across R_y. This is

Equation 11.13

Figure 11.7. Opamp dc stabilized with feedback resistor network. The output voltage is applied back to the input to then drive the output toward a smaller value. The voltage across R_y will be about equal to V_off and V_O is forced to near zero.

(Dc V_O is used, as this is a no-signal or bias state under consideration.) This voltage will cancel ...
