Abstract
A driver circuit has first and second output drivers, monitor circuitry for deriving control signals related to driven signal levels, and supply circuitry responsive to the control signals for controlling the supply voltage to the output drivers. The monitor circuitry can be connected to monitor the voltage at the supply inputs of the output drivers for deriving the control signals. Alternatively, the monitor circuitry can be connected directly to monitor driven output levels from the drivers. In the latter case, the output levels to be monitored are rectified. The monitor circuitry can comprise first and second operational amplifiers for comparing a monitored voltage from first and second output drivers, respectively, to a first and second reference voltages, respectively. The supply circuitry can comprise first and second constant current sources, for example field effect transistors.
