Norton_inverting_ac_amplifier_with_NVSUBBE_SUB_biasing

This circuit shows both an inverting ac amplifier and a third method for biasing. The input bias voltage VBE establishes a current through R3 to ground, This current comes from the amplifier output, so VO must rise to a level that causes the current to flow through R2. VO is calculated from the ratio of R2 and R3, as shown by the equations. When this NVBE biasing is used, R1 and R2 are established first, then R3 is added for the desired VO.
