Methods and systems for sensing load conditions and for adjusting output current drive according to the sensed load conditions to maintain one or more signal characteristics within a desired range. Load (102) conditions are sensed (106) by monitoring one or more signal characteristics that are affected by load conditions, such as voltage changes with respect to time. Output current drive (104) is then adjusted (105), as needed, to maintain the one or more desired signal characteristics.The dV/dt can be monitored by coupling a capacitance (106) to the output signal, generating a current (118) with the capacitance, and generating a voltage from the current. Depending upon the load conditions, a supplemental current (124) is generated and/or adjusted and added to the output signal (116) to maintain the desired signal characteristics within a desired range. |
