ABSTRACT:
A segmented voltage function is generated at the output of a primary differential amplifier having an input voltage connected to the noninverting terminal. As the input voltage increases at the noninverting amplifier input, the output increases with the same slope until a voltage as sensed at the inverting input of the amplifier equals a first breakpoint. The inverting input to the primary differential amplifier connects to a feedback circuit that also includes a plurality of secondary differential comparator amplifiers coupled to a voltage ladder network. Each of the secondary differential amplifiers has a noninverting input connected to a separate voltage on the ladder network. The inverting input of each of the secondary differential amplifiers is connected to a feedback loop. At the first breakpoint one of the secondary differential comparator amplifiers switches into a conduction mode through a gain resistor connected to the output of the secondary amplifier and the inverting input of the primary differential amplifier. This clamps the gain resistor to the first breakpoint voltage established by the ladder network. All other comparator amplifiers in the feedback loop are operating in a comparator "off" mode and will remain in this mode until the output of the primary differential amplifier equals the breakpoint voltages established by the noninverting input terminal of the comparator amplifiers. As each of the comparator amplifiers switches into a conduction mode, the associated gain resistor is clamped to the breakpoint voltage and the gain of the primary differential amplifier is progressively increased to a desired level.
