Abstract:
An audio system can include an amplifier having two parallel drivers, one having common source transistors and one having common drain transistors, also called source following. At low signals, the source followers dominate the open-loop gain signal path, while large signals cause the common source transistors to be dominant. At low signal amplitudes, the common source transistor gain is reduced and the common drain transistors provide the load current. At a pre-determined level of signal amplitude, the common source transistors take over and provide the current load. A calibration system for a DAC is also provided. The calibration system measures individual cell performance in the DAC, then stores its digital equivalent in a coefficient storage. Then, a quantizer can refer to the stored coefficients when selecting the appropriate final quantized digital value.

Claim (Index 13):
The amplifier according to  claim 10  further comprising a feedback resistor coupled between the input and the output of the amplifier, in which the feedback resistor produces a voltage output for the amplifier.
