摘要： A method, apparatus, and system are described in which a hybrid of two standard types of voltage regulators is formed. The hybrid voltage regulator may share a switching waveform with a switching waveform generator already in use on the circuit board, which may be a switching voltage regulator. This switching waveform acts as a control waveform for the hybrid voltage regulator, thus eliminating the need for another controller. The hybrid voltage regulator combines the functionality of a linear voltage regulator and a switching voltage regulator into one circuit. The shared switching waveform controls during operation as a switching voltage regulator. A second control waveform is generated by a control amplifier, which compares the regulated output voltage to a reference voltage. The second control waveform controls during operation as a linear voltage regulator.

摘要： Line drivers with extended linearity are described herein. In one embodiment, shown in Fig.4, an example of a line driver includes, but is not limited to, a first amplifier (401)having a first input, a second amplifier (402) having a second input, the first and second amplifiers driving a load of a communication line, and a trans-conductance stage (403 and 404) device coupled to the first and second amplifiers. The trans-conductance stage device is configured to sense a first error voltage across the first input of the first amplifier and to provide a first feedback to the second input of the second amplifier. The trans-conductance stage device is configured to sense a second error voltage across the second input of the second.
