Inverting configuration

Other circuits are of course possible. For example, Figure 4 shows an inverting

configuration where the main architecture (without any filtering and biasing of the input at

Vcc/2) has a gain of –R2/R1.

Figure 4. Inverting configuration

To design a circuit with a differential output, we can simply cascade an inverting stage (with

R2 = R1) to the output of the first stage amplifier.

Both outputs would then be with the same amplitude, but with a phase inversion.
