摘要： A regulated power supply provides a regulated supply voltage at a preselected level under normal operating conditions. When power demands of the circuitry driven by the supply requires a higher voltage, the supply adapts to supply such a higher voltage. Such a supply can be used with automotive electronic circuitry, and can supply voltages up to approximately the voltage available on an automobile battery when such higher power demands occur. The higher supply voltages remain regulated, and return to normal levels when the extra power requirement is removed.

摘要： A signal is amplified with a plurality of amplifiers (12-18), each amplifier having a reference port (22), a reference node (C) coupled to the reference port, and a signal port (22), and each amplifier being supplied by a power source (30-36) with operating potential with respect to the reference node that is coupled to the reference port of that amplifier. The amplifiers (12-18) are cascaded in a manner selected so that the output of a first amplifier (12) (which receives the signal to be amplified at its input port) drives the reference node (22) of a second amplifier (14), and the reference node (22) of the first amplifier (12) provides an input at the signal port (20) of the second amplifier (14), whereby the first and second amplifiers are directly coupled together to amplify the applied signal.
