Norton_noninverting_ac_amplifier_with_voltage_reference_biasing

Published:2009/7/17 4:10:00 Author:Jessie | From:SeekIC

This circuit shows both a noninverting ac amplifier and a second method for dc biasing. As in the case of the Fig. 11-32 circuit, the ac gain of this circuit is set by the ratio of the feedback resistor to the input resistor. However, the small-signal impedance of the internal diode at the (+) input must be added to the values of R1 when calculating gain, as shown by the equations.
