Abstract: A process compensation circuit for an inverting element of a CMOS device, including a duplicate inverting element connected in parallel with the inverting element of the CMOS device. An upside-down inverter stage has an input connected to the output of the duplicate inverting element, and an output connected to the output of the inverting element of the CMOS device. The upside-down inverter stage is configured to counteract a delayed logic transition of the output of the inverting element of the CMOS device in the event of a process skew between NFET and PFET devices.

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.
