WebTHEORY: Current shunt feedback circuit shows two transistor in cascade with feedback from the second emitter to the first base through the resistor R F. we verify that this connection produces negative feedback. The voltage V i2 is much larger than V i1 because of the voltage gain of Q 1. Also V i2 0is 180 out of phase with V i1 Web4. The amplifier used in this design was selected as a low-cost, low-input offset voltage amplifier. In general, cost is further reduced by selecting an amplifier with a higher offset (TLV9062). Use the Component Selection section to confirm that the system errors meet your requirements when selecting different amplifiers.
