- Differential amp has 6 dB lower noise, twice the bandwidthThe traditional three op-amp differential amplifier's signal to noise ratio can be improved by 6 dB by adding a resistor and slightly changing the connections. There is a trade-off though: The traditional topology has a high input impedance, whereas the low-noise version has...Apr 14, 2015
