Abstract: Disclosed is a high-swing voltage-mode transmitter or line driver. The transmitter can operate over a wide range of supply voltages. Increasing the available output swing merely involves increasing the supply voltage; the circuit adapts to maintain the desired output impedance. This allows for a tradeoff between output amplitude and power consumption. Another advantage of the proposed architecture is that it compensates for process, voltage, and temperature (PVT) and mismatch variations so as to keep rise and fall times matched. This feature reduces common-mode noise and hence EMI in systems in which the transmitter is used.

Abstract: A method for driving a non-linear load element. On account of the non-linear interrelationship between the voltage and the current at the load element and the related non-linear dependence of the power loss on the quantities “voltage” and “current”, an adjustment of the switching speed only on the basis of the power loss in the switching element cannot be carried out with non-linear load elements without being confronted with undesirable switching losses and related electromagnetic noise fields. Therefore, the load current currently flowing in the load element is picked up in addition to the currently determined power loss in the switching element, and the switching speed of the switching element is controlled in dependence on the determined power loss and on the current picked up. The switching speed can be optimally adjusted when driving the non-linear load elements by means of PWM.
