ABSTRACT:
An output of a common mode differential amplifier is initialized to a known state, which includes inputting a voltage to a network conductor of an electronic assembly, where the network conductor is coupled to a first input node of a first differential input of the amplifier. The amplifier is on an integrated circuit chip of the assembly and has a self-bias node. Circuitry of the amplifier normally adjusts to obtain an equilibrium voltage on the self-bias node in response to the inputted voltages. To initialize the amplifier output, however, preset circuitry on the integrated circuit chip overrides the normal equilibrium voltage on the self-bias node, forcing the self-bias node to a predetermined voltage regardless of the amplifier input voltages. In response, the amplifier produces an desired initial output state on a first output node of the amplifier.
