High current source design

WebMeasuring the dynamics of a continuously moving target, at the nanoscale level, such as of a bearing raceway or any other vibrating element, requires a contactless measurement. A mission that can be easily carried out by a capacitive probe. The current flowing through the sensor has to remain constant regardless of the changes in the sensors’ output … Web2. I want to design a high side variable current source: Power source (Vacc) is an accumulator whose output varies between 9V and 7V. I need output DC current values between 10mA and 100mA. I need it to be high side, so the load (RLOAD) is referred to ground. RLOAD is between 1 ohm and 60ohm.
