    摘要: A driver circuit, in accordance with one example, includes a controllable current source operably coupled to the load and configured to sink or source a first current in accordance with a control signal. A controllable switch is responsive to an input signal, operably coupled to the current source, and configured to take over, or not, the first current in accordance with an input signal. The first current is directed as a load current through the load when the controllable switch is driven into a blocking state. The first current is directed through the controllable switch when the controllable switch is driven into a conducting state thus bypassing the load. An input signal includes a first series of pulses defining the desired load current waveform in accordance with a desired modulation scheme.
