  • Output control method for a digital controller of a source measure unit
    Patent number: 10291116
    Abstract: An output control method for a controller includes the following steps. At each of detection time points, the controller detects a detection voltage value and a detection current value of a load. In a voltage control mode, the controller generates a setting parameter to control the power amplifier according to part of the detection voltage values. In a current control mode, the controller generates the setting parameter to control the power amplifier according to part of the detection current values. When the controller switches to the voltage control mode or the current control mode, the controller determines a ratio between the detection current value and the detection voltage value at one of the detection time points and the setting parameter is generated according to the ratio. Therefore, the bandwidth is substantially the same no matter if the controller operates in the voltage control mode or the current control mode.
