摘要： An amplifier. The novel amplifier includes a first circuit for receiving and amplifying an input signal and outputting an output signal, and a second circuit for supplying power to the first circuit, wherein the power supplied varies in accordance with variations in the output signal. The second circuit includes a bootstrapping circuit adapted to regulate the voltages across any transistors in the signal path such that the voltages remain constant. In an illustrative embodiment, the second circuit bootstraps the voltages across a PMOS current source that acts as the load to an input stage, as well as a Darlington pair in an output stage of the amplifier.

摘要： A high speed switch. The novel switch includes an input circuit having a transistor Q1 for receiving an input signal, a first mechanism for providing a path from an output of Q1 to an output terminal, and a second mechanism for receiving a control signal and in accordance therewith reducing the conductivity of the path during a mute mode. The first mechanism includes a first circuit for providing a first path from an output of Q1 to a first node, and a second circuit for providing a second path connecting the first node to the output terminal. The second mechanism is adapted to apply a signal to the first node during the mute mode such that the first and second circuits are off or partially conducting. The switch also includes a circuit for clamping the first node to a first predetermined voltage during the mute mode.
