asked Jan 15 in Linear Integrated Circuits by Julian (38.2k points)

How an AC amplifier can be powered by a single supply voltage, produces voltage swing?

(a) By inserting a voltage divider at the inverting input

(b) By inserting a voltage divider at the non-inverting input

(c) By inserting a voltage divider at the output

(d) By inserting a voltage divider at the feedback circuit

This question was posed to me in an online quiz.

My question comes from AC Amplifiers with Single Supply Voltage topic in chapter Operational Amplifier Applications of Linear Integrated Circuits

answered Mar 16 by Chris (39.8k points)

The correct option is (b) By inserting a voltage divider at the non-inverting input

Grasp the essence with: A positive dc level is intentionally inserted using a voltage-divider network at the non-inverting input terminal, so that output can swing both positively as well as negatively.
