In this instance, the closed-loop amplifier is resistively configured as an inverting gain stage with DC gain, A VCL, set at 60 dB (1000V/V), 40 dB (100V/V), and 20 dB (10V/V) distinct levels. It is ...

Figure 8: Two kinds of balanced voltage amplifier stage: Type 1 gives more open loop gain, but no better open loop linearity. Type 2 the circuit originated by Lender. Two possible versions are shown ...

Operating at 12V and delivering 5W from a 600mVp-p input, TI is claiming a 28dB improvement in THD+N at 100Hz compared with an open-loop Class-D designs. “You have to be careful with specifications ...

It runs from zero (at p = 0) to open loop (at p = 1). Since it's dependent on the circuit layout, feedback-capacitor C is best optimized empirically. A good place to start, however, is C = 1/(2π ...
