Balanced transformer-less amplifier and an offset detection and correction system therefore |
摘要 |
A balanced transformer-less amplifier includes a system for detecting and correcting DC offset across the output terminals of the amplifier. The output signal is digitized, counted during a predetermined period, and the result of the counting is used to derive a DC correction signal which is fed back to the input of the amplifier.
