    Abstract: An auto-zeroing sample-hold amplifier capable of tracking an input voltage and, when designated, sampling and accurately holding an input voltage with no gain or offset errors includes input and output buffers with complementary, equal-magnitude offsets for minimizing offset voltage errors. An input voltage is sampled across a primary hold capacitor as well as a secondary hold capacitor [at the amplifier output to] in a sample mode. In a hold mode, the capacitors, in conjunction with the buffers and a transconductance amplifier, form a negative feedback loop around the transconductance amplifier to hold the sampled voltage and reduced voltage excursions at the output of the sample-hold amplifier. A special cancellation switch and capacitor are included for differentially cancelling voltage errors caused by switch charge feed-through onto the primary hold capacitor.

    Abstract: Coating compositions, methods of applying the coating compositions, and articles incorporating the coating compositions are provided. The coating compositions are useful for coating a variety of substrates to improve the appearance and printability of the substrates. The coating compositions incorporate pigment system, a binder, and a thickener system. The thickener system incorporates a polyvinyl alcohol polymer and a boron containing compound such as boric acid. The coating compositions exhibit viscosity characteristics equal or superior to coating compositions incorporating conventional thickeners while providing cost advantages over conventional thickener systems.
