Digital driver circuit

摘要: A digital driver circuit with increased maximum output voltage amplitude and therefore also current for constant power supply voltages is provided. sensing resistor replaces the conventional source transistor in stage of circuit. In addition, control applied to an earlier driver. An automatic scheme created which keeps across equal a DC reference maintains or by actively level shifting DATA drive signals correct level. This eliminates necessity incorporate safety margin simultaneously increases available amplitude. Therefore, utilizing moving circuit, present invention provides amplitudes modulated devices. another embodiment, keeping Mark-Bar signal corresponding input data.
