Abstract
A current rise in fall time limited voltage follow is shown having a voltage driver providing a voltage signal into a current driver. The output of the current driver is a load varying in resistance, for example, as the number or combination of devices connected to the load vary. The maximum current into the load and the maximum rise time of the current into the load is limited at the output of the current driver to a maximum by the input impedance of the current driver. The rise time and the current into the load may increase until the resistance of the load is substantially that of the current driver input resistance reduced by a factor of N. The factor N is the maximum current capability of the output of the current driver related to the current driver input current generated by the voltage signal from the voltage driver. The current into the load and the maximum rise time of the load will increase until the load resistance R is less than the input impedance of the current driver divided by the current multiple N at the output of the current driver related to the current at the input of the current driver.
