The experimental system of the differential amplification micro actuator was composed of the micro actuator, vibration isolation platform, temperature controller, constant current source, displacement measuring system, constant temperature water cooling system and magnetic field detection system.
Constant current source (Digital Source-meter Unit (SMU)).
It also contains a built in bridge excitation supply which can be configured either as a 0 - 10 V constant voltage source with optional remote sensing or as a 0 - 25 mA constant current source.
that says that better temperature stability can be achieved by using constant current source to set the bias point of the diodes, which leads to the current biasing approach.
The MCUs also include a Charge Time Measurement Unit (CTMU) with a constant current source that can be used for mTouch(TM) capacitive sensing, ultrasonic flow measurement and many other sensors.
Whether the LED string voltage is higher than the voltage supply available in the system or the capability of driving multiple LED strings is needed, the most important consideration for any LED driver is the constant current source.
ISFET is mostly used in circuit with constant current source connected to drain.
Editor's Note: To satisfy the operating temperature of 70[degrees]K, the LVDTs use a constant current source, rather than the typical AC excitation voltage.
The constant current source with automatic gain control feedback can be derived using the internal D/A converter and a simple algorithm running in the MCU.
The attenuation decreases with increasing temperature when PIN diodes are biased by a very high voltage source and high value of bias resistor (equivalent to constant current source bias).
The MCUs also include a Charge Time Measurement Unit (CTMU) with a constant current source that can be used for mTouch[TM] capacitive sensing, ultrasonic flow measurement and many other sensors.
