发明名称 DC OFFSET MITIGATION IN A SINGLE-SUPPLY AMPLIFIER
摘要 <p>An amplifier is described which includes a first loop including a first amplifier stage having an offset voltage associated therewith. An output stage includes two switching devices in a bridge configuration configured to be coupled between a supply voltage and ground. An output of the bridge configuration is configured to be coupled to a load. The first loop is characterized by a first gain. A decoupling capacitor is configured to be coupled to the load. A second loop which includes the first amplifier stage is configured to charge the decoupling capacitor to a first voltage generated with reference to the offset voltage before operation of the switching devices is enabled. The second loop is characterized by a second gain. The first and second gains are substantially the same such that when operation of the switching devices is enabled a second voltage at the output of the half-bridge configuration is substantially the same as the first voltage.</p>
