    摘要： A bootstrap circuit (150) comprises a pair of drivers (250,350) coupled together so as to form a bootstrap node (750), and a bipolar transistor (265) coupled to the bootstrap node (750). A method of using a bipolar transistor (265) in such a bootstrap circuit comprises the step of applying a voltage signal (V in ) having a magnitude sufficient to activate the bipolar transistor. In another embodiment of the invention, a bootstrap circuit comprises a pair of drivers coupled together so as to form a bootstrap node, a transistor coupled to the bootstrap node, and a clamping circuit coupled to the transistor.

    摘要： A method of switching a switched-capacitor circuit reduces signal-dependent distortion resulting from the switching operation. Two single-pole, double-throw switches (11,12) in the array, having the switched capacitor (13) between the common terminals thereof, are alternately switched without the use of an intermediate (no-make) state.
