explain how an instrumentation amplifier is able to rpovide better cmrr compared to a regular difference amplifier

Sagot :

In comparison to a typical op-amp, an instrumentation amplifier has lower noise and a greater common mode rejection ratio.

When a differential signal needs to be amplified in the presence of a potential substantial common-mode input, such as significant electromagnetic interference, a high CMRR is necessary (EMI). Audio transmission via balanced lines for sound reinforcement or recording is one example.

When there is significant noise present, an instrumentation amplifier (IA) is utilised to give a lot of gain for very low-level signals. High gain, a large common-mode rejection ratio (CMRR), and extremely high input impedance are IAs' main characteristics.

We may raise the CMRR by either lowering common mode voltage gain or raising differential voltage gain; the greater the CMRR, the better the op-capacity amp's to reject unwanted noise and EMI. Emitter resistance RE should be raised to boost CMRR.
