Abstract: An electrical device (e.g., an integrated circuit) includes an amplifier, a configurable common mode gain trim circuit, and a memory. The configurable common mode gain trim circuit is coupled to the amplifier. The memory is configured to include trim data that is usable during an initialization process for the electrical device to configure the impedance matching circuit.
