A derivative measurement circuit is configured to sample the input voltage of an input line to determine the time-derivative of the input voltage. A plurality of time-interleaved analog-to-digital converters (ADCs) are configured to convert respective input-voltage samples that are sampled at different times. The ADCs do not convert the input-voltage samples having respective time-derivatives that are above a predetermined threshold magnitude or that are relatively high to limit sampling clock jitter and sampling clock skew.

Sampling jitter and skew tolerant analog-to-digital converters

A push-pull dynamic amplifier is operable in reset and amplification phases. The amplifier includes first NMOS and PMOS input transistors that are electrically coupled to a first input terminal and a first output terminal. Second NMOS and PMOS input transistors are electrically coupled to a second input terminal and a second output terminal. First and second reset switches are electrically coupled to the first and second output terminals, respectively. A power supply switch is electrically coupled to the first and the second PMOS transistors, and a ground switch is electrically coupled to the first and the second NMOS transistors. During the reset phase, the reset switches are closed and the power supply switch and the ground switch are opened. During the amplification phase, the reset switches are opened and the power supply switch and the ground switch are closed.

An adhesion promoter comprises a reaction product of: a) a polyepoxide; b) an aminosilane represented by the formula HNRR. Rand Rindependently represent &#x2014;Z&#x2014;SiL. Each Z independently represents a divalent linking group having from 1 to 12 carbon atoms, and each L independently represents a hydrolyzable group; and c) an isocyanatosilane represented by the formula O&#x2550;C&#x2550;N&#x2014;Z&#x2014;SiL, wherein Z and L are as previously defined. The adhesion promoter may be used to treat a surface of a substrate such as an abrasive particle, which may be included in a resin-bond abrasive article.

A multipath sampling circuit includes an input line electrically having an input voltage, a plurality of voltage amplifiers in parallel electrically with one another, each voltage amplifier having a respective input electrically coupled in series with the input line, each voltage amplifier having a different gain and a different saturation voltage; and a plurality of track-and-hold circuits. The track-and-hold circuits have a first state in which a respective input of each track-and-hold circuit is electrically coupled to an output of a respective amplifier. The track-and-hold circuits have a second state in which the respective input of each track-and-hold circuit is electrically decoupled from the output of the respective amplifier. The track-and-hold circuits can be electrically coupled to a summing circuit, a buffer amplifier, or an operational amplifier.
