发明名称 Split amplifier architecture for cross talk cancellation
摘要 An amplifier circuit includes a first amplifier and a second amplifier and sets of switching devices controlled by a bistate control signal. The bistate control signal is in the first state to cause the first and second sets of switching devices to configure the first amplifier and the second amplifier in a positive parallel configuration and the bistate control signal is in the second state to cause the first and second sets of switching devices to configure the first amplifier and the second amplifier in a negative parallel configuration. When the bistate control signal switches states at each sample cycle of the amplifier circuit, the first amplifier and the second amplifier toggle between the positive parallel configuration and the negative parallel configurations to cancel out crosstalk signals stored at the positive and negative input terminals of the first and second amplifier circuit.
