The first common mode voltage (Vreg/2) and second common mode voltage (Vbatt/2) are unequal.
A differential amplifier substracts the generated common mode voltage on the ground line from the common mode voltage on the source input line, leaving only the source voltage as an output.
A common mode voltage is measured, and the phase and amplitude of the exciting source is controlled to reduce the difference between the common mode voltage and reference voltage of a voltage detector.
The excitation voltage (101) at one terminal (102) with respect to a common mode voltage is opposite in polarity from the voltage of the second terminal (104) with respect to the common mode voltage.
Zero vectors are selected to minimize the common mode voltage.
The common-mode compensation current is used to compensate for the common-mode voltage of the inputs.
An optional common-mode feedback circuit can keep the output common-mode voltage substantially constant.
The first and second capacitors are both coupled to a single common-mode voltage to provide a predefined common-mode output voltage.
A compensation voltage (Ukomp) is determined on the basis of the common-mode voltage (Ugl).
The common-mode voltage of an externally-generated reference clock can vary from the common-mode voltage of the internally-generated feedback clock.
All clocks are differential and have a common- mode voltage.
In an embodiment, a driver may have multiple operating modes for each potential supply voltage or common-mode voltage.
A switched-mode level-shifter shifts a differential voltage superimposed on a common-mode voltage.
The high impedance at the terminals (6, 8) of the write head (2) enables the common-mode voltage across the write head (2) to be fixed at any desired voltage value by means of a common-mode circuit.
A common-mode voltage (VCM) of a differential signal (INP, INM) from a measuring circuit (304) and an average for the common- mode voltage of the differential signal (VCMA) from an averaging circuit (302) are measured.
The interfaces can derive the common-mode voltage from received signals as the reference voltage, rather than from a dedicated voltage reference.
The four state modulation results in a common mode voltage in the absence of audio.
In the pre-charge state, both differential signals are pre-charged to the common mode voltage, which is also the crossover voltage.
In one implementation, the common-mode voltage of a differential driver circuit is regulated via a feedback signal.
Common-mode voltage = (A + B)/2 – the reference voltage (usually 0 V or ground)
